Description

The XC5200 Field-Programmable Gate Array Family is

engineered to deliver low cost. Building on experiences

gained with three previous successful SRAM FPGA fami-

lies, the XC5200 family brings a robust feature set to pro-

grammable logic design. The VersaBlock™ logic module,

the VersaRing I/O interface, and a rich hierarchy of inter-

connect resources combine to enhance design flexibility

and reduce time-to-market. Complete support for the

XC5200 family is delivere d through the fam iliar Xilinx so ft-

ware e nviro nment . The XC52 00 fami ly i s ful ly s uppo rted o n

popular workstation and PC platforms. Popular design

entry methods are fully supported, including ABEL, sche-

matic capture, VHDL, and Verilog HDL synthesis. Design-

ers utilizing logic synthesis can use their existing tools to

XC5200 Family Compared to

XC4000/Spartan™ and XC3000

Series

For read ers already f amiliar with the XC4 000/Spar tan and

XC3000 FPGA Families, this section describes significant

differences between them and the XC5200 family. Unless

otherwise indicated, comparisons refer to both

XC4000/Spartan a n d XC3000 devices.

Conf igura ble Logic Bloc k (CLB) Resour ces

Each XC5 200 C LB c ontai n s fo ur inde pe nde nt 4- inp ut fu nc -

tion generators and four registers, which are configured as

four indepe ndent L ogic Cells ™ (LCs). The re gisters in e ach

XC5200 LC are optionally configurable as edge-triggered

D-type flip-flops or as transparent level-sensitive latches.

The XC5200 CLB includes dedicated carry logic that pro-

vides fast arithmetic carry capability. The dedicated carry

logic may also be used to cascade function generators for

implement ing wide arit hmetic funct ions.

XC4000 family:

XC5200 devices have no wide edge

decoders. Wide decoders are implemented using cascade

logic. A lthough sacrificing s peed fo r some de signs, lac k of

wide edge decoders reduces the die area and hence cost

of the X C5200.

XC4000/Spartan family:

XC5200 dedicated carry logic

differs from that of the XC4000/Spartan family in that the

sum is generated in an additional function generator in the

adjacent column. This design reduces XC5200 die size and

hence cost for many applications. Note, however, that a

loadable up/down counter requires the same number of

functio n gener ators in bo th families. X C3000 has no de di-

cated car ry.

XC4000/Spartan family:

XC5200 lookup tables are opti-

mized for co st and hence cannot im plement RAM.

Input/Outpu t Block (IO B) Resou rce s

The XC5200 family maintains footprint compatibility with

the XC4000 family, but not with the XC3000 family.

To minimize cost and maximize the number of I/O per Logic

Cell, the XC5200 I/O does not include fli p-flops or latches.

For high performance paths, the XC5200 family provides

direct connections from each IOB to the registers in the

adjacent CLB in order to emulate IOB register s.

Each XC5200 I/O Pin provides a programmable delay ele-

ment to contro l input s et-up ti me. Thi s element can be us ed

to avoid potential hold-time problems. Each XC5200 I/O

Pin is capable of 8-mA sourc e and si nk currents.

IEEE 1149.1-type boundary scan is supported in each

XC5200 I/O.

Routing Reso ur ces

The XC5200 family provides a flexible coupling of logic and

local ro uti ng resou rces call ed the VersaB lock . The XC5 200

V er saBloc k elemen t inc ludes t he CLB, a Loc al In tercon nect

Matrix (LIM), and direct connects to neighboring Versa-

Blocks.

The XC5200 provides four global buffers for clocking or

high-f a nou t co nt ro l s igna l s. Ea ch bu ffer may b e sou r ced by

means of its dedicated pa d or from any internal source.

Each XC5 200 TB UF ca n dr i ve up t o t wo h ori zo nt al and t w o

vertical Longlines. There are no internal pull-ups for

XC5200 Longlines.

Configura tion an d Read back

The XC5200 supports a new configuration mode called

Express mode.

XC4000/Spartan family:

The XC5200 family provides a

global reset but not a global set.

XC5200 devic es use a different co nfiguration proc ess than

that of t he XC 30 00 f ami ly, bu t use t he s ame p ro ce ss as t h e

XC4000 and Spartan families.

XC30 00 f amily:

Although their configuration processes dif-

fer, XC5200 devices may be used in daisy chains with

XC3000 devices.

XC3000 family:

The XC5200 PROGRAM pin is a sin-

gle-function input pin that overrides all other inputs. The

PROGRAM pin does not exist in XC3000.

Architectural Overview

Figure 1 presents a simplified, conceptual overview of the

XC5200 architecture. Similar to conventional FPGAs, the

XC5200 family consists of programmable IOBs, program-

mable logic blocks, and programmable interconnect. Unlike

other FPGAs, however, the logic and local routing

resources of the XC5200 family are combined in flexible

Ver saBlocks (Figure 2). General-purpose routing connects

to the VersaBlock through the General Routing Matrix

(GRM).

VersaBlock: Abundant Local Routing Plus

Versatile Logic

The ba sic l ogic el emen t in each VersaBlo ck s truct ure is the

Logic Cell, shown in Figure 3. Each LC contains a 4-input

function generator (F), a storage device (FD), and control

logic. There are five independent inputs and three outputs

to each LC. The independence of the inputs and outputs

allows the software to maximize the resource utilization

within each LC. Each Logic Cell also contains a direct

feedthrough path that does not sacrifice the use of either

the fun ction gen erator or th e register ; this featu re is a first

for F PGAs. The storage dev ice is conf igurabl e as either a D

flip-flop or a latch. The control logic consists of carry logic

for fast implementation of arithmetic functions, which can

also be configured as a cascade chain allowing decode of

very wide input functions.

The XC5200 CLB consists of four LCs, as shown in

Figure 4. Each CLB has 20 independent inputs and 12

independent outputs. The top and bottom pairs of LCs can

be configured to implement 5-input functions. The chal-

lenge of FPGA implementation software has always been

to maximize the usage of logic resources. The XC5200

family addresses this issue by surrounding each CLB with

two types of local interconnect — the Local Interconnect

Matrix (LIM) and direct connects. These two interconnect

resources, combined with the CLB, form the VersaBlock,

repr esented in Figure 2.

The LIM provides 100% connectivity of the inputs and out-

puts of each LC in a given CLB. The benefit of the LIM is

that no general routing resources are required to connect

feedback paths within a CLB. The LIM connects to the

GRM via 24 bidirectional nodes.

The direct connects allow i mmediat e connections to neigh-

boring CLBs, once again without using any of the general

interconnect. These two layers of local routing resource

improve the gran ularity of the architecture, effectively mak-

ing the XC5200 family a “sea of logic cells.” Each

Versa-Block has four 3-state buffers that share a common

enable line and directly drive horizontal and vertical Lon-

glines, creating robust on-chip bussing capability. The

Ve rsaBlock allows fa st, local impl ementation of logic func-

tions, effec tively imple menting user design s in a hierarch i-

cal fashion. These resources also minimize local routing

congestion and improve the efficiency of the general inter-

connect, which is used for connecting larger groups of

logic. It is this combination of both fine-grain and

coar se-grain ar chitecture attr ibutes that max imize logic uti-

lization in the XC5200 family. This symmetrical structure

takes full advantage of the third metal layer, freeing the

placement software to pack user logic optimally with mini-

mal routing restrictions.

VersaRing I/O Interface

The interface between the IOBs and core logic has been

redesigned in the XC5200 famil y. The I OBs are completely

decoupled from the core logic. The XC5200 IOBs contain

dedicated boundary-scan logic for added board-level test-

ability, but do not include input or output registers. This

approach allows a maximum number of IOBs to be placed

around the device, improving the I/O-to-gate ratio and

decreasing the cost per I/O. A “freeway” of interconnect

cells surrounding the device forms the VersaRing, which

provides connections from the IOBs to the internal logic.

These incremental routing resources provide abundant

connections from each IOB to the nearest VersaBlock, in

addition to Longline connections surrounding the device.

The VersaRing eliminates the historic trade-off between

high logic utilization and pin placement flexibility. These

increm ent al e dge re so urce s giv e u se rs incre ase d fle xibilit y

in preassigning (i.e., locking) I/O pins before completing

their log ic designs. T his ability a ccelerate s time-to-ma rket,

since PCBs and other system components can be manu-

factured concurrent with the logic design.

General Routing Matrix

The GRM is functionally similar to the switch matrices

found in other architectures, but it is novel in its tight cou-

pling to the logic resources contained in the VersaBlocks.

Advanced simulation tools were used during the develop-

ment of the XC5200 architecture to determine the optimal

level of routing resources required. The XC5200 family

contains six levels of interconnect hierarchy — a series of

single-length lines, double-length lines, and Longlines all

routed through the GRM. The direct connects, LIM, and

logic-cell feedthrough are contained within each

Versa-Block. Throughout the XC5200 interc onnect, an effi-

cient m ultiplexing sc heme, in c ombination with three layer

metal ( TLM), w as us ed to imp rove th e over all efficiency of

silicon usage.

Performance Ov erv iew

The XC5200 family has been benchmarked with many

designs running synchronous clock rates beyond 66 MHz.

The perf ormance of an y desi gn depends on the circui t to be

implem en te d, a nd t he d elay thro ug h th e co m bin at or ial an d

sequential logic elements, plus the delay in the intercon-

nect routing. A rough estimate of timing can be made by

assuming 3-6 ns per logic level, which includes direct-con-

nect routing delays, depending on speed grade. More

accurate estimations can be made using the information in

the Switching Characteristic Guideline section.

Taking Ad van tage of Reconfigu ration

FPGA de vice s can be recon figur ed to ch ange l ogic fu ncti on

while re sident in th e system . This cap ability giv es the sys-

tem designer a new degree of freedom not available with

any othe r typ e of logic.

Hardware can be changed as easily as software. Design

updates or modifications are easy, and can be made to

produ cts alrea dy in the fie l d. An FPGA ca n ev en be re co n-

figured dynamically to perform different functions at differ-

ent times .

Reconfigurable logic can be used to implement system

self-diagnost ics, create systems capable of being reconfig-

ured for different environments or operations, or implement

multi-purpose hardware for a given application. As an

added benefit, using reconfigurable FPGA devices simpli-

fies hardware design and debugging and shortens product

time-to-market.

Detailed Functional Description

Configura ble Logic Blocks (CLBs)

Figure 4 shows the logic in the XC5200 CLB, which con-

sists of four Logic Cells (LC[3:0]). Each Logic Cell consists

of an independent 4-input Lookup Table (LUT), and a

D-Type flip- flop or latch with common c lock, clock enable,

and clear, but individually selectable clock polarity. Addi-

tional logic features provided in the CLB are:

• An independent 5-i nput LU T by combining two 4-input

LUTs.

• High-speed carry propagate logic.

• High-speed pattern decoding.

• High-speed direct connection t o flip-flop D-inputs.

• Individual selection of either a transparent,

level-sensitive latch or a D flip-flop.

• Four 3-state buffers with a shared Output Enable.

5-Input Functions

Figure 5 illustrates how the outputs from the LUTs from

LC0 and LC1 can be combined with a 2:1 multiplexer

(F5_MUX) to provide a 5-input function. The outputs from

the LUTs of LC2 and LC3 can be similarly combi ned.

Carry Functi on

The XC5200 family supports a carry-logic feature that

enhances the performance of arithmetic functions such as

counte rs, a dders, etc. A c arry m ultiplexe r (CY_ MUX) sym -

bol is used to indicate the XC5200 carry logic. This symbol

represents the dedicated 2:1 multiplexer in each LC that

performs the one-bit high-speed carry propagate per logic

cell (four bits per CLB).

While the carry propagate is performed inside the LC, an

adjacent LC must be used to complete the arithmetic func-

tion. Figure 6 represents an example of an adder function.

The carry propagate is performed on the CLB shown,

which al so gener ates the hal f-su m for the four -bit ad der . An

adjacen t CLB is responsible for XORing the half-sum with

the corresponding carry-out. Thus an adder or counter

requires two LCs per bit. Notice that the carry chain

requires an initialization stage, which the XC5200 family

accomplishes using the carry initialize (CY_INIT) macro

and one ad ditional LC. The carry chain can propagate ver-

tically up a colum n of CLBs.

The XC5200 library contains a set of Relationally-Placed

Macros (RPMs) and arithmetic functions designed to take

advantage of the dedicated carry logic. Using and modify-

ing thes e macros make s it much easier to implem ent cus-

tomized RPMs, freeing the designer from the need to

become an expert on architectures.

Cascade Function

Each CY_MUX can be connected to the CY_MUX in the

adjacent LC to provide cascadable decode logic. Figure 7

illustrate s ho w the 4- input fu nc tion ge ner ators can be co n-

figured to take advantage of these four cascaded

CY_MUX es. Not e that AND and OR ca scadi ng are sp eci fic

cases of a general decode. In AND cascading all bits are

decoded equal to logic one, while in OR cascading all bits

are decoded equal to logic zero. The flexibility of the L UT

achieves this result. The XC5200 library contains gate

macr os designed to take advantage of this fun ction.

CLB Flip-Flops and Latches

The CLB can pass the combinatorial output(s) to the inter-

connect network, but can also store the combinatorial

results or other incoming data in flip-flops, and connect

their outputs to the interconnect network as well. The CLB

stor age elements can also be configured as latche s.

Data Inputs and Outputs

The source of a storage element data input is programma-

ble. It is driven by the function F, or by the Direct In (DI)

block input. The flip-flops or latches drive the Q CLB out-

puts.

Four fast feed-through paths from DI to DO are available,

as shown in Figure 4. This bypass is sometimes used by

the automated router to repower internal signals. In addi-

tion to the storage element (Q) and direct (DO) outputs,

there is a combinatorial output (X) that is always sourced

by the Lookup Table.

The four edge-triggered D-type flip-flops or level-sensitive

latches have common clock (CK) and clock enable (CE)

inputs. Any of the clock inputs can also be permanently

enabled. Storage element functionality is described in

Table 3.

Clock Input

ments with individual polarity control. Any inverter placed

on the clock input is automatically absorbed into the CLB.

Clock Enable

The cloc k enable signal (CE) is active High. The CE pin is

shared by the four storage elements. If left unconnected

for any, the clock enable for that storage element defaults

to th e active state. CE is not invertible within the CLB.

active High. It is not invertible within the CLB.

Global Reset

A separate Global Reset line clears each storage element

during power-up, reconfiguration, or when a dedicated

Reset net is driven active. This global net (GR) does not

compete with other routing resources; it uses a dedicated

distribu tio n ne two r k.

GR can be driven from any user-programmable pin as a

global reset input. To use this global net, place an input pad

and input buffer in the schematic or HDL code, driving the

GR pin of the STARTUP symbol. (See Figure 9.) A specific

pin location can be assigned to this input using a LOC

attribute or property, just as with any other user-program-

mable pad. An inverter can optionally be inserted after the

input buffer to invert the sense of the Global Reset signal.

Alt ernatively, GR can be driven from any inte rnal node.

Using FPGA Flip-Flops and Latches

The abundance of flip-flops in the XC5200 Series invites

pipel ined designs . This is a powe rful w ay of inc reasi ng per -

formance by breaking the function into smaller subfunc-

tions and executing them i n parallel, passin g on the res u lts

throu gh p i pe li ne f li p- f lops . Thi s me th od sh oul d be seri o us ly

considered wherever throughput is more important than

latency.

To include a CLB flip-flop, place the appropriate library

symbo l. For ex a mpl e, FD CE is a D -ty pe f li p-f lo p wit h c loc k

enable and asynchronous clear. The corresponding latch

symbol is called LDCE.

In XC5200-Series devices, the flip-flops can be used as

registers or shift registers without blocking the function

generators from performing a different, perhaps unrelated

task. This ability increases the functional capacity of the

devices.

The CLB setup time is specified between the function gen-

erator inp uts and the clock input CK. Therefore, the speci-

fied CLB flip-flop setup time includes the delay through the

function generator.

Three-State Buffers

The XC5200 family has four dedicated Three-State Buffers

(TBUFs, or BUFTs in the schematic library) per CLB (see

Figure 9). The four buffers are individually configurable

through four configuration bits to operate as simple

non-inverting buffers or in 3-state mode. When in 3-state

mode the CLB output enable (TS) control signal drives the

enable to all four buffers. Each TBUF can drive up to two

horiz ontal an d/or t wo verti cal Lon glines . These 3- state buf f-

ers can be used to implement multiplexed or bidirectional

buses on the horizontal or vertical longlines, saving logic

resources.

The 3 -state buffer ena ble is an active -High 3-sta te (i.e. an

active-Low enabl e), as s hown in Table 4.

Another 3-state buffer with similar access is located near

each I/O block along the ri ght and left edges of t he array.

The longlines driven by the 3-state buffers have a weak

keeper at each end. This circuit prevents undefined float-

ing levels. However, it is overridden by any driver. To

ensur e th e lo n glin e goes high wh en n o bu ffers ar e on , a dd

Figure 10 shows how to use the 3-state buffers to imple-

ment a multiplexer. The selection is accomplished by the

buffer 3-state signal.

Input/ Ou tput Blocks

User-configurable input/output blocks (IOBs) provide the

interface between external package pins and the internal

logic. E ach IOB controls one package pin and can be co n-

figured for input , output, or bidirectional signa ls.

The I/O block, shown in Figure 11, consists of an input

buffer and an output buffer. The output driver is an 8-mA

full-rail CMOS buffer with 3-state control. Two slew-rate

control modes are supported to minimize bus transients.

Both t he o ut put bu ffer and t h e 3-s t at e co ntro l a re in ve rt i ble .

The input buffer has globally selected CMOS or TTL input

thres holds. T he input buf fer is i nvertibl e and also provides a

programmable delay line to assure reliable chip-to-chip

set-up and hold times. Minimum ESD protection is 3 KV

using the Human Body Model.

IOB Input Signals

The XC5200 inputs can be globally configured for either

TTL (1.2V) or CMOS thresholds, using an option in the bit-

stream generation software. There is a slight hysteresis of

Optional Delay Guarantees Zero Hold Time

XC520 0 devices do not have storag e elements in the IO Bs.

However, XC5200 IOBs can be efficiently routed to CLB

flip-flops or latches to stor e the I/O signals.

The d ata inpu t to th e re gister can opt iona lly be d elaye d by

several nanoseconds. With the delay enabled, the setup

time o f the input flip -flop is increa sed so that no rmal clock

routing does not result in a positive hold-time requirement.

A positive hold time requirement can lead to unreliable,

temperature- or processing-dependent operation.

The input flip-flop setup time is defined between the data

measured at the device I/O pin and the clock input at the

CLB (not at the clock pin). Any routing delay from the

device clock pin to the clock input of the CLB must, there-

fore , be subtra cted from this setup time t o arrive at the real

setup time requirement relative to the device pins. A short

specified setup time might, therefore, result in a negative

setup time at the device pins, i.e., a positive hold-time

requirement.

When a dela y is i nser t ed on th e data l ine , mor e c loc k del ay

can be tolerated without causing a positive hold-time

requi rement. Sufficient de lay eliminat es the po ssibility of a

data hold-time requirement at the external pin. The maxi-

mum delay is therefore inserted as the software default.

The XC5200 IOB has a one-tap delay element: either the

delay is insert ed (defau lt), or it is not. The dela y guarante es

a zero hold time with respect to clocks routed through any

of the XC5200 global clock buffers. (See “Global Lines” on

page 96 for a description of the global clock buffers in the

XC5200.) For a shorter input register setup time, with

IOB Output Signals

Output signals can be optionally inverted within the IOB,

and pass directly to the pad. As with the inputs, a CLB

flip-flop or latch can be used to store the output signal.

An active-High 3-state sign al can b e used to place the out-

put buffer in a high-impedance state, implementing 3-state

outputs or bidirectional I/O. Under configuration control,

the output (OUT) and output 3-state (T) signals can be

inverted. The polarity of these signals is independently

confi gured for each IOB.

The XC 5200 d evice s pro vid e a gua rant eed outp ut si nk cu r-

rent of 8 mA.

Supported destinations for XC5200-Series device outputs

are shown in Table 6.(For a detailed discussion of how to

interface betw een 5 V and 3.3 V devices, see the 3V Prod-

ucts sectio n of

The Programma ble Logic Data Book

An ou tput can be conf igu red a s ope n-dr ain (op en -coll ect or)

by placing an OBUFT symbol in a schematic or HDL code,

then tying the 3-state pin (T) to the output signal, and the

input pin (I) to Ground. (See Figure 12.)

Table 6: Supported Destinations for XC520 0-Series

Outputs

Output Slew Rate

The slew rate of each output buffer is, by default, reduced,

to minimiz e powe r bus tran sients when sw itching no n-cr iti-

cal signal s. For critical sig nals, attach a FAST a ttribute or

prop erty to the ou tput buffer or flip-flop.

For XC5200 devices, maximum total capacitive load for

simultaneous fast mode switching in the same direction is

200 pF for all package pins between each Power/Ground

pin pair. For some XC5200 devices, additional internal

Power/Ground pin pairs are connected to special Power

and Ground planes within the packages, to reduce ground

bounce.

For slew-rate limited outputs this total is two times larger for

each device type: 400 pF for XC5200 devices. This maxi-

mum capacitive load should not be exceeded, as it can

resu lt in ground bounce of grea ter than 1. 5 V ampli tude and

more than 5 ns duration. This level of ground bounce may

cause undesired transient behavior on an output, or in the

internal logic. This restriction is common to all high -speed

digital ICs, and is not particular to Xilinx or the XC5200

Series.

XC5200-Series devices have a feature called “Soft

Start -up, ” desi gned to red uce gr ound bo unce when al l out-

puts are turned on simultaneously at the end of configura-

tion. When the configuration process is finished and the

device starts up, the first activation of the outputs is auto-

matically slew-rate limited. Immediately following the initial

activation of the I/O, the slew rate of the individual outputs

is determined by the individual configuration option for

each IOB.

Global Three-State

A separate Global 3-State line (not shown in Figure 11)

forces all FPGA outputs to the high-impedance state,

unless boundary scan is enabled and is executing an

EXTEST instruction. This global net (GTS) does not com-

pete with othe r rou ting r esou rces; it u ses a d edic ate d dist ri-

bution netw ork.

GTS can be driven from any user-programmable pin as a

global 3-state input. To use this global net, place an input

pad and input buffer in the schematic or HDL code, driving

the GTS pin of the STARTUP symbol. A specific pin loca-

tion can be assigned to this input using a LOC attribute or

propert y, ju st as with any other user-pr ogrammab le pad. An

inverter can optionally be inserted after the input buffer to

inver t the sens e of th e Global 3 -State s ignal. Using GTS i s

similar to Global Reset. See Figure 8 on page 90 for

details. Alternatively, GTS can be driven from any internal

node.

Other IOB Options

There are a number of other programmable options in the

XC5200-Series IOB.

Pull-up and Pull-down Resistors

Programmable IOB pull-up and pull-down resistors are

useful for tying unused pins to Vcc or Ground to minimize

power consumption and reduce noise sensitivity. The con-

transistor that pulls to Ground.

The value of these resistors is 20 kΩ − 100 kΩ. This high

value makes them unsuitable as wired-AND pull-up resis-

tors.

The pul l-up re sistor s for most u ser-pr ogrammabl e IOBs ar e

active during the configuration process. See Table 13 on

page 124 for a list of pins with pull-ups active before and

during configuration.

After configuration, voltage levels of unused pads, bonded

or unbonded, must be valid logic levels, to reduce noise

sensitivity and avoid excess current. Therefore, by default,

unused pads are configured with the internal pull-up resis-

tor active. Alternatively, they can be individually configured

with the pull-down resistor, or as a driven output, or to be

driven by an external source. To activate the internal

pull-up, attach the PULLUP library component to the net

attached to the pad. To activate the internal pull-down,

attach the PULLDOWN library component to the net

attached to the pad.

JTAG Support

Embedded logic attached to the IOBs contains test struc-

tures compatible with IEEE Standard 1149.1 for boundary

scan testing, simplifying board-level testing. More informa-

tion is provided in “Boundary Scan” on page 98.

Oscillator

XC5200 dev ices includ e an intern al oscillator. This osc illa-

tor is used to clock the powe r-on tim e-ou t, cl ear co nfigur a-

tion memory, and source CCLK in Master configuration

modes . The osc illat or ru ns at a n omi n al 12 M Hz fr e qu en cy

that varies with pr ocess, Vcc, and temperature. The output

CCLK frequency is selectable as 1 MHz (default), 6 MHz,

or 12 MHz.

The XC5200 oscillator divides the internal 12-MHz clock or

a user clock. The user then has the choice of dividing by 4,

16, 64, or 256 for the “OSC1” output and dividing by 2, 8,

32, 128, 1024, 4096, 16384, or 65536 for the “OSC2” out-

put. The division is specified via a “DIVIDEn_BY=x”

attribute on the symbol, where n=1 for OSC1, or n=2 for

OSC2. These frequencies can vary by as much as -50% or

+ 50%.

The OSC5 macro is used where an internal oscillator is

required. The CK_DIV macro is applicable when a user

clock input is spec ified (se e Figure 13).

VersaBlock Routing

The General Routing Matrix (GRM) connects to the

Versa-Block via 24 bidirectional ports (M0-M23). Excluding

direct connections, global nets, and 3-statable Longlines,

all VersaBlock i np ut s and ou tp ut s con ne ct to th e GR M vi a

these 24 ports. Four 3-statable unidirectional signals

(TQ0-TQ3) drive out of the VersaBlock directly onto the

horizontal and vertical Longlines. Two horizontal global

nets and two vertical global nets connect directly to every

CLB cloc k pin; the y can conn ect to ot her CLB inp uts via th e

GRM. Each CLB also has four unidirectional direct con-

nects to each of its four neighboring CLBs. These direct

connects can also feed directly back to the CLB (see

Figure 14).

In ad dit i on , ea ch C LB ha s 1 6 dir ec t in p ut s, four d ire ct con -

nections from each of the neighboring CLBs. These direct

connections provide high-speed local routing that

bypasses the GRM.

Local Interconnect Matrix

The L ocal Int erconne ct Matr ix (LIM) is b uilt from in put and

output multiplexers. The 13 CLB outputs (12 LC outputs

plus a Vcc/GND signal) connect to the eight VersaBlock

outputs via the output multiplexers, which consist of eight

fully populated 13-to-1 multiplexers. Of the eight

VersaBlock outputs, four signals drive each neighboring

CLB dir ectly, and pro vide a dire ct feedba ck path to the input

multiplexers. The four remaining multiplexer outputs can

drive the GRM through four TBUFs (TQ0-TQ3). All eight

multiplexer outputs can connect to the GRM through the

bidi rect i on al M0- M23 s i gnal s . Al l ei gh t s i gna ls a lso c on ne ct

CLB inputs have several possible sources: the 24 signals

from the GRM, 16 direct connections from neighboring

VersaBlocks, four signals from global, low-skew buffers,

and the four signals from the CLB output multiplexers.

Unlike the output multiplexers, the input multiplexers are

not fully populated; i.e., only a subset of the available sig-

nals ca n be conne cted to a g iven CLB in put. The fle xibility

of LUT input swapping and LUT mapping compensates for

this limitation. For example, if a 2-input NAND gate is

required, it can be mapped into any of the four LUTs, and

use any two of the four input s to the LUT.

Direct Connects

The unidirectional direct-connect segments are connected

to the logic input/output pins through the CLB input and out-

put mul t ip le xe r ar ra ys , and th us by pa ss t he g ene ra l rou ti ng

matr ix altogether. These lines increase the routin g channel

utilization, while simultaneously reducing the delay

incurred i n speed-critical connections.

The direct connects also provide a high-speed path from

the edge CLBs to the VersaRing input/output buffers, and

thus reduce pin-to-pin set-up time, clock-to-out, and combi-

nation al propagation delay. Direc t connects from the input

buffers to the CLB DI pin (direct flip-flop input) are only

available on the left and right edges of the device. CLB

look-up table inputs and combinatorial/registered outputs

have direct connects to input/output buffers on all four

sides.

The direct connects are ideal for developing customized

RPM cells. Using direct connects improves the macro per-

formance, and leaves the other routing channels intact for

improved r outing. Direct connects can also route through a

CLB using one of the four cel l-feedthro ugh paths.

Matrix through a hierarchy of different-length metal seg-

ments in both the horizontal and vertical directions. A pro-

grammable interconnect point (PIP) establishes an electri-

cal connection between two wire segments. The PIP, con-

sisting of a pass transistor switch controlled by a memory

element, provides bidirectional (in some cases, unidirec-

tional) connection between two adjoining wires. A collec-

tion of PIPs inside the General Routing Matrix and in the

Local Interconnect Matrix provides connectivity between

various types of metal segments. A hierarchy of PIPs and

associated routing segments combine to provide a power-

ful interconnect hie r archy:

• Forty bidire ctional single-length segments per CLB

neighboring CLBs in four directions.

segme nts span the width an d height of the chip,

respectively.

Two low-skew horizontal and vertical unidirectional glo-

bal-line segments span each row and column of the chip,

respectively.

Single- and Double-Length Lines

The single- and double-length bidirectional line segments

make up the bulk of the routing channels. The dou-

ble-length lines hop across every other CLB to reduce the

propag ati on dela ys in s peed -crit ical net s. Rege nerat ing t he

signal strength is recommended after traversing three or

four s uch segm ents. Xilinx place-an d-route so ftware a uto-

matically connects buffers in the path of the signal as nec-

essary. Single- and double-length lines cannot drive onto

Longlines and global lines; Longlines and global lines can,

however, drive onto single- and double-length lines. As a

general rule, Longline and global-line connections to the

general routing matrix are unidirectional, with the signal

direction from these lines toward the routing matrix.

Longlines

Longl ines ar e used for hig h-fan-o ut sig nals, 3 -state b usses ,

low-skew nets, and faraway d e stinations. Row a nd column

split ter PI Ps in the mid dle of the ar ray ef fecti vely doub le the

total number of Longlines by electrically dividing them into

two separated half-lines. Longlines are driven by the

3-state b uffer s in e a ch CLB, an d a r e d riv en by sim ilar bu ff-

ers at the periphery of the array from the VersaRing I/O

Interface.

Bus- orient ed desi gns ar e easil y imp lemented by usin g Lon-

gli nes i n co nju nctio n wit h t he 3 -st ate buffers in th e CL B and

in the VersaRing. Additionally, weak keeper cells at the

periphery retain the last valid logic level on the Longlines

when al l buffers are in 3-stat e mode.

Longlines connect to the single-length or double-length

lines, or to the logic inside the CLB, through the General

Routing Matrix. The only manner in which a Longline can

be driven is through the four 3-state buffers; therefore, a

Longline-to-Longline or single-line-to-Longline connection

through PIPs in the General Routing Mat rix is not possible.

Again, as a general rule, long- and global-line connections

to the General Routing Matrix are unidirectional, with the

signal dir ection from these lines toward the routing matrix.

The XC52 00 f amil y h as no p ul l-u ps on t he e nds o f t he Lon -

glines sourced by TBUFs, unlike the XC4000 Series. Con-

sequen t l y, wired fu nc ti o ns (i . e., WAND and WO RAND ) a nd

wide multiplexing functions requiring pull-ups for undefined

stat es (i. e ., b us ap pl ic at ion s) must be i mp leme nt ed in a di f -

ferent way. In the case of the wired functions, the same

functionality can be achieved by taking advantage of the

carry/cascade logic described above, implementing a wide

logic fu nction in p lace of the wired functio n. In the c ase of

3-stat e bus a pplicat ions, t he user must i nsure that all states

of the multiplexing function are defined. This process is as

simple as adding an additional TBUF to drive the bus High

when the previously undefined states are activated.

Global Lines

Global buffers in Xilinx FPGAs are special buffers that drive

a dedicated routing network called Global Lines, as shown

in Figure 16. This network is intended for high-fanout

cloc ks or othe r contro l signal s, to maxi mize speed and min-

imiz e skewing while distributing the sign al to many loads.

The XC5200 family has a total of four global buffers (BUFG

symbol in the library), each with its own dedicated routing

channel. Two are distributed vertically and two horizontally

throughout the FPGA.

The global lines provide direct input only to the CLB clock

pins. The global lines also connect to the General Routing

Matrix to provide access from these lines to the function

generators and other control signals.

Four clock input pads at the corners of the chip, as shown

in Figure 16, prov ide a high -speed , low- skew cl ock netwo rk

to each of the four global-line buffers. In addition to the ded-

icated pad, the global lines can be sourced by internal

logic. PIPs from several routing channels within the Ver-

saRing can also be configured to drive the global-line buff-

ers.

Details of all the programmable interconnect for a CLB is

shown in Figure 17.

VersaR ing Inp ut/Ou tpu t Interface

The VersaRing, shown in Figure 18, is positioned between

the core logic and the pad ring; it has all the routing

resources of a VersaBlock without the CLB logic. The Ver-

saRing decouples the core logic from the I/O pads. Each

VersaRi n g Cel l provides up to four pad-cell con nections on

one side, and connects directly to the CLB ports on the

other sid e.

Boundary Scan

The “bed o f nails” has been the trad itional met hod of testi ng

electronic assemblies. This approach has become less

appropriate, due to closer pin spacing and more sophisti-

cated assembly methods like surface-mount technology

and multi-layer boards. The IEEE boun dary scan sta ndard

1149.1 was developed to facilitate board-level testing of

electronic assemblies. Design and test engineers can

imbed a standard test logic structure in their device to

achieve high fault coverage for I/O and internal logic. This

structure is easily implemented with a four-pin interface on

any bou ndary scan- compatib le IC. IEEE 1149.1- compatible

devi ces may be seri al daisy -chaine d toge ther , connec ted in

parallel, or a combination of the two.

XC5200 devices support all the mandatory boundary-scan

instructions specified in the IEEE standard 1149.1. A Test

Access Port (TAP) and registers are provided that imple-

ment the EXTEST, SAMPLE/PRELOAD, and BYPASS

instructions. The TAP can also support two USERCODE

instructions. When the boundary scan configuration option

is selected, three normal user I/O pins become dedicated

inputs for these functions. Another user output pin

beco mes the dedicated boun dary scan output.

Boundary-scan operation is independent of individual IOB

configuration and package type. All IOBs are treated as

independently controlled bidirectional pins, including any

unbonded IOBs. Retaining the bidirectional test capability

after configuration prov ides flexibility for interconnect test-

ing.

Also, internal signals can be captured during EXTEST by

connecting them to unbonded IOBs, or to the unused out-

puts in IOBs used as unidirectional input pins. This tech-

nique partially compensates for the lack of INTEST

support.

The user can serially load commands and data into these

devices to control the driving of their outputs and to exam-

ine their inputs. This method is an improvement over

bed-of-nails testing. It avoids the need to over-drive device

outputs, and it reduces the user interface to four pins. An

optio nal fift h pin, a re set for t he control logic, is descri bed in

the standard but is not implemented in Xilinx devices.

The dedicated on-c hip logic implementing the IEEE 1149.1

funct i ons i n cl u des a 16- st a te mac hin e, an i nstr uc t i on r eg is-

ter and a number of data registers. The functional details

can be found in the IEEE 1149.1 specification and are also

discussed in the Xilinx application note XAPP 017:

“Bound-

ary Scan in XC 4000 and XC5200 Series devices”

Figure 19 on page 99 is a diagram of the XC5200-Series

boundary scan logic. It includes three bits of Data Register

per IOB, the IEEE 11 49.1 Test Access Port controller, and

the Instruction Register with dec odes.

The public boundary-scan instructions are always available

prior to conf igurati on. Afte r config uration, the pub lic inst ruc-

tions and any USERCODE instructions are only available if

specified in the design. While SAMPLE and BYPASS are

available during configuration, it is recommended that

boundary-scan operations not be performed during this

transitory period.

In addition to the test instructions outlined above, the

bound ary-sca n circui try c an be used t o confi gure the FPGA

XC52 00-Ser ies de vic es ca n al so be confi gure d th rough the

boundary scan logic. See XAPP 017 for more information.

Data Registers

The primary data register is the boundary scan register.

For each IOB pin in the FPGA, bonded or not, it includes

three bits for In, Out and 3-State Control. Non-IOB pins

have appropriate partial bit population for In or Out only.

PROGRAM, CCLK and DONE are not included in the

boundary scan register. Each EXTEST CAPTURE-DR

state capt ures all In, Out, and 3-State pins.

The data register also includes the following non-pin bits:

TDO.T, and TDO.O, which are always bits 0 and 1 of the

data register, respectively, and BSCANT.UPD, which is

always the last bit of the data register. These three bound-

ary scan bit s are spe cia l-pur p ose Xilinx te st sig nal s.

The other standard data register is the single flip-flop

BYPASS register. It synchronizes data being passed

through the FPGA to the next downstream boundary scan

device.

The FPGA provides two additional data registers that can

be specified using the BSCAN macro. The FPGA provides

two user pins (BSCAN.SEL1 and BSCAN.SEL2) which are

the deco des of two use r instruction s, USER 1 and USER 2.

For these instructions, two corresponding pins

(BSCA N.TDO1 an d BSCAN.T DO2) allow user sc an data to

be shifted out on TDO. The data register clock

(BSCAN.DRCK) is available for control of test logic which

the user may wish to implement with CLBs. The NAND of

TCK and RUN-TEST -IDLE is also provided (BSCAN.IDLE).

Instruction Set

The XC5200-Series boundary scan instruction set also

includes instructions to configure the device and read back

the configuration data. The instruction set is coded as

show n in Table 7.

Table 7: Boundary Scan Instructions

Bit Sequenc e

The bit sequence within each IOB is: 3-State, Out, In. The

data-register cells for the TAP pins TMS, TCK, and TDI

have an OR-gate that permanently disables the output

buffer if boundary-scan operation is selected. Conse-

quentl y , it is i mpossi ble for t he outp uts in IO Bs used b y TAP

inputs to conflict with TAP operation. TAP data is taken

directly from the pin, and cannot be overwritten by injected

boundary-scan data. However , if necessary, it is possible to

drive the clock input from boundary scan. The external

clock source is 3-stated, and the clock net is driven with

boundary scan data through the output driver in the

cloc k-pad I OB. If t he cl ock-pa d IOBs ar e used f or non-c lock

signals, the data may be overwritten normally.

Pull-up and pull-down resistors remain active during

boundary scan. Before and during configuration, all pins

are pulled up. After configuration, the choice of internal

pull-up or pull-down resistor must be taken into account

when designing test vectors to detect open-circuit PC

traces.

From a cavity-up view of the chip (as shown in XDE or

Epic), starting in the upper right chip corner, the boundary

scan data-register bits are ordered as shown in Table 8.

Even if the boundary scan symbol is used in a schematic,

the input pins TMS, TCK, and TDI can still be used as

input s to be routed t o interna l logi c. Care must be ta ken not

to force the chip into an undesired boundary scan state by

inadvertently applying boundary scan input patterns to

these pins. The simplest way to prevent this is to keep

TMS High, and then apply whatever signal is desired to TDI

and TCK.

Avoidi ng Inadvertent Bound ary Scan

If TMS or TCK is used as user I/O, care must be taken to

ensure that at leas t one o f thes e p ins is he ld con sta nt du r-

ing configuration. In some applications, a situation may

occur where TMS or TCK is driven during configuration.

This may cause the device to go into boundary scan mode

and disrupt the configura tion process.

To prevent activation of boundary scan during configura-

tion, do either of the following:

• TMS: Tie High to put the Test Access Port controller

in a benign RESET state

• TCK: Tie High or L ow—do not toggle this clock input.

Power Distribution

Power fo r the FP GA is dis tribu ted th rough a grid to ach ieve

high noise immunity and isolation between logic and I/O.

Inside the FPGA, a dedicated Vcc and Ground ring sur-

rounding the logic array provides power to the I/O drivers,

as shown in Figure 21. An independent matrix of Vcc and

Grou nd lin es suppl ies the interio r logic of the device .

This power distribution grid provides a stable supply and

ground for al l internal logic, providing the external package

power pins are all c onnected and appropriatel y decoupled.

Typically, a 0.1 µF capacitor connected near the Vcc and

Ground pins of the package will provide adequate decou-

pling.

Outp ut buffe rs capabl e of drivi ng/sinki ng the spe cifi ed 8 mA

loads u nder specif ied worst-ca se conditio ns may be c apa-

ble of driving/sinking up to 10 times as much current under

best case conditions.

Noise can be reduced by minimizing external load capaci-

tance and reducing simultaneous output transitions in the

same direction. It may also be benefi cial to loca te heav ily

loaded out put bu f fers near the Gro und p ads. The I/O B lock

output buffers have a slew-rate limited mode (default)

which should be used where output rise and fall times are

not speed-critical.

Pin Descriptions

There are three types of pins in the XC5200-Series

devices:

• Permanently dedicat ed pins

• User I/O pins that can have special functions

• Unrest r icted user-programmable I/O pins.

Befor e and dur ing co nfigurat ion, all out puts no t used fo r the

configuration process are 3-stated and pulled high with a

20 kΩ - 100 kΩ pull-up resistor.

After configuration, if an IOB is unused it is configured as

an inpu t with a 20 kΩ - 100 kΩ pull-up resis tor.

CCLK I or O I

During configuration, Configuration Clock (CCLK) is an output in Master modes or Asyn-

chronous Peripheral mode, but is an input in Slave mode, Synchronous Peripher al

mode , and Express mode. After configuration, CCLK has a weak pull-up resistor and

can be selected as the Readback Clock. There is no CCLK High time restriction on

XC5200-Ser ies devices, except during Readback. See “Violating the Maximum High

and Low Time Specif icatio n for the Read back Clo ck” on pag e 113 for an expla natio n of

this exception.

DONE I/O O

DONE i s a bid irect ion al si gnal w ith an o ption al int erna l pull -up resis tor. As an ou tput , it

indi cates the completion of the c onfig urati on proces s. As an i nput, a Low leve l on

DONE can be co nfigured to delay the global logic initialization and the enabling of out-

puts.

The exact timing, the clock source for the Low-to- High transition, and the optional

pull -up resi stor ar e select ed as opti ons in the program t hat creat es the co nfigurat ion bit -

stream. The resistor is i nclud ed by default.

PROGRAM II

PROGRAM is an active Low input that forces the FPGA to clear its configuration me m-

ory. I t is us ed t o ini t iat e a co nf igur at i on c ycl e . Whe n P ROG RAM go es High , the FPGA

executes a complete clear cycle, before it goes into a WAIT state and rele ases I NIT.

The PROGRAM pin has an optional weak pull-up after configuration.

User I/O Pins That Can Have Special Functions

RDY/BUSY OI/O

Duri ng Peripheral mode configuration, this p in indic ates w hen it is appropriate to write

another byt e of data into the FPGA. The same status is also available on D7 in A syn-

chronous Peripheral mode, if a read operation is performed when the device is selected.

After configuration, RDY/BUSY is a user -p ro gr a mm a ble I/O pi n.

RDY/BUSY is pulled High with a high-impedance pull-up prior to INIT going High.

RCLK OI/O

Duri ng Master Parallel configuration, each change on the A0-A17 outputs is pr eceded

by a rising edg e on R CL K , a redundant output signal. RCLK is useful for clocked

PROMs. It is rarely used during configuration. After configuration, RCLK is a user- pro-

grammable I/O pin.

M0, M1 , M2 I I/O

As Mod e input s, these pins are sampled before the start of configuration to determine

the confi g uration mode to be used. After configuration, M0, M1, and M2 bec o me us-

er-programmable I/O.

Duri ng confi guratio n, these pins h ave weak pul l-up resistors . For t he most po pular con -

fig uration m ode, Slave Serial, t he mode pin s can thus b e left un connecte d. A pull-d own

resistor value of 3.3 kΩ is rec ommended for ot her modes.

TDO O O

If bo undary scan i s used, this pi n is the Test D ata Out put. I f boundar y scan is not used,

this pin is a 3-state output, after configuration is completed.

This pin can be user output only when called out by special schematic definitions. To

If boundary scan is used, these pins are Test Data In, Test Clock, and Test Mode Select

HDC O I/O High During Configuration (HDC) is driven High until the I/O go active. It is available as

a control output indicating that configuration is not yet completed. After configuration,

HDC is a user-programmable I/O pin.

LDC OI/O

Low During Configuration (LDC) is dri ven Low unti l the I/ O go activ e. It is avai lable as a

LDC is a user-programmable I/O pin.

INIT I/O I/O

Before and during configuration, INIT is a bidirectional signal. A 1 kΩ - 10 kΩ extern al

pull-up r e sistor is r ecommended.

As an active-Low open-drain output, INIT is held Low during the power stabilization and

internal clearing of the configuration memor y. As an active-L ow input, it can be used

to hold the FPGA in the internal WAIT state before the star t of configuration. Master

mode dev ices stay in a WAIT state an addit ional 50 to 25 0 µs after INIT has gone High.

Duri ng configuration, a Low on this output indicates that a configuration data error has

occurred. After the I/O go ac tive, INIT is a user-progr ammable I/O pin.

GCK1 -

Pull-up I or I/O

Four Global inputs each drive a dedicated internal global net with short delay and min-

imal skew. These i nternal glob al nets can also be dr iven from int ernal logic. If not use d

to drive a global net, any of these pins is a user-programma ble I/O pin.

The G CK1-GCK 4 pins provide the shorte st path to the four Global Buffers. Any input

pad symbol connected directly to the input of a BUFG symbol is automatically placed on

one of these pins.

CS0, CS1,

WS, RS II/O

These four inputs are used in Asynchronous Peripheral mode. The chip is selected

when CS0 is Low and CS1 is High. While the chip is selected, a Low on Write Strobe

(WS) loads the data present on the D0 - D7 inputs into the internal data buffer. A Low

on Read Strobe (RS) changes D 7 in to a s ta tu s out pu t — H igh i f Read y , L ow i f Bu sy —

and drive s D 0 - D6 High.

In Ex press mode, CS1 is used as a serial-enable signal for daisy-chaining.

WS and RS shou ld be mutu ally exc lusiv e, but if b oth are Low simul taneousl y, the Write

Strobe overrides. After configurat ion, these are user-programmable I/O pins.

A0 - A17 O I/O During Master Parallel configuration, these 18 output pins address the configuration

EPROM. After configuration, they are user-programmable I/O pins.

D0 - D7 I I/O Du ring Mast er Para llel, P eripheral , and Ex press co nfigur ation, t hese eig ht input pins re -

DIN I I/O During Slave Serial or Master Serial configuration, DIN is the serial configuration data

input receiving data on the rising edge of CCLK. During Parallel configurat ion, DIN is

the D0 input. After configuration, DIN is a user-programmable I/O pin.

DOUT O I/O

During co nfiguration in any mode but Express mode, DOUT is the serial configuration

data output that c an drive the DIN of dais y-chain ed slav e FPGAs. DOUT dat a chan ges

In Ex press mode, DOUT is the status output that can drive the CS1 of daisy-chained

Configuration

Confi guration is the process of loading design-speci fic pro-

gram ming d ata i nto one or more FPGAs to define the func-

tional operation of the internal blocks and their

interconnections. This is somewhat like loading the com-

mand registers of a programmable peripheral chip.

XC5200- S er ies dev ic es use s e ve ral hun dr ed b its o f con fi g -

uration data per CLB and its associated interconnects.

Each configuration bit defines the state of a static memory

cell that co nt ro ls e ith er a f un ction loo k- u p table b it, a m u lti-

plexer input, or an interconnect pass transistor. The devel-

opment system translates the design into a netlist file. It

automatically partitions, places and routes the logic and

generates the configuration data in PROM format.

Special Purpose Pins

Three configuration mode pins (M2, M1, M0) are sampled

prior to configuration to determine the configuration mode.

After configuration, these pins can be used as auxiliary I/O

connections. The development system does not use these

resources unless they are explicitly specified in the design

entry. This is done by placing a special pad symbol called

MD2, MD 1, or MD0 instead of the input or output pad sym-

bol.

In XC5200-Series devices, the mode pins have weak

pull-up resistors during configuration. With all three mode

pins Hig h, Sl ave S e rial m ode i s se lec te d, w hic h i s t he m os t

popular configuration mode. Therefore, for the most com-

mon configuration mode, the mode pins can be left uncon-

nected. (Note, however, that the internal pull-up resistor

valu e can be a s hi gh as 10 0 kΩ.) Aft er co nfi gura tio n, th ese

pins can individually have weak pull-up or pull-down resis-

tors, as specified in the design. A pull-down resistor value

of 3.3kΩ is rec ommended.

These pins are located in the lower left chip corner and are

near the readback nets. This location allows convenient

routing if compatibility with the XC2000 and XC3000 family

conventions of M0/RT, M1/RD is desired.

Configurat ion Mode s

XC5200 devices have seven configuration modes. These

mode s are selec ted b y a 3 -bit i nput code a ppli ed to t he M2 ,

M1, and M0 inputs. There are three self-loading Master

mode s, two Pe r iph er a l mod es, and a S er ial Sl av e mo d e,

Note :*Peripheral Sy nchronous can be considered byte-wide

Slave Parallel

whic h is u se d prim ari l y f o r d ai sy -c ha i ned de vi ce s. T he se v-

enth mode, called Express mode, is an additional slave

mode that allows high-speed parallel configuration. The

coding for mode selectio n is shown in Table 10.

Note that the smallest package, VQ64, only supports the

Master Serial, Slave Serial, an d Express modes.A detai led

description of each configuration mode, with timing infor-

matio n, is inclu ded late r in t his da ta shee t. Du ring con figu -

ration, some of the I/O pins are used temporarily for the

configuration process. All pins used during configuration

are sh own in Table 13 on pag e 124.

Master Modes

The three Master modes use an internal oscillator to gener-

ate a Conf igurat ion Cloc k ( CCLK) for d riv ing pote ntial sla ve

devices. They also generate address and timing for exter-

nal PROM(s) contain ing the configuration data.

Master Parallel (Up or Down) modes generate the CCLK

signal and PROM addresses and receive byte parallel

data. The data is internally serialized into the FPGA

data-frame format. The up and down selection generates

starting addresses at either zero or 3FFFF, for compatibility

with different microprocessor addressing conventions. The

figurati on data in serial f orm fro m a Xilinx s erial-co nfigura-

tion PRO M .

CCLK sp eed is s elect able as 1 MHz (d efault ), 6 MH z, or 12

MHz. Configuration always starts at the default slow fre-

quency, then can switch to the higher frequency during the

first frame. Frequency tolerance is -50% to +50%.

Peripheral Modes

The two Peripheral modes accept byte-wide data from a

bus. A RDY/BUSY status is available as a handshake sig-

nal. In Asynchronous Peripheral mode, the internal oscilla-

tor generates a CCLK burst signal that serializes the

byte- w ide d at a. CC LK c an als o dr i ve s l ave de vi ce s. I n t he

synchronous mode, an externally supplied clock input to

CCLK serializes the data.

Slave Serial Mode

In Slave Serial mode, the FPGA receives serial configura-

tion data on the rising edge of CCLK and, after loading its

configuration, passes additional data out, resynchronized

on the next falling edge of CCLK.

Multiple slave devices with identical configurations can be

wired with parallel DIN inputs. In this way, multiple devices

can be configured simultaneously.

Serial Daisy Chain

Multiple devices with different configurations can be con-

nected together in a “daisy chain,” and a single combine d

bitstre am used to configure the chain of slav e devices.

To configure a daisy chain of devices, wire the CCLK pins

of all devices in parallel, as shown in Figure 28 on page

114. Connect the DOUT of each device to the DIN of the

next. The lead or master FPGA and following slaves each

passes resynchronized configuration data coming from a

single source. The header data, including the length count,

is passed through and is captured by each FPGA when it

recognizes the 0010 preamble. Following the length-count

data, each FPGA outputs a High on DOUT until it has

received its required number of data frames.

After an FPGA has received its configuration data, it

passes on any additio nal frame start bits and configurati o n

data on DOUT. When the total number of configuration

clocks applied af ter memory initialization equals th e value

of the 24-bit length count, the FPGAs begin the start-up

sequence and become operational together. FPGA I/O are

normal ly rel eased two CCLK cycl es after the la st confi gura-

tion bit is received. Figure 25 on page 109 shows the

start-up t iming for an XC5200-Series dev ice.

The daisy-chained bitstream is not simply a concatenation

of the individ ual bitstr eams. The PR OM f ile form atte r mu st

be us ed t o c ombine the bits trea ms for a d ais y-cha ined c on-

figuration.

Multi-Family Daisy Chain

All Xilinx FPGAs of the XC2000, XC3000, XC4000, and

XC5200 S erie s us e a co mpati ble b it stream form at an d ca n,

therefore, be connected in a daisy chain in an arbitrary

sequence. There is, however, one limitation. If the chain

contai n s XC5 200 -Se ri es d ev i ce s, t h e ma st e r n orm al ly c an-

not be an XC2000 or XC3000 device.

The reas on f or t his r ule i s sh ow n in F igur e 25 on p age 10 9.

Since all devices in the chain store the same length count

value and generate or receive one common sequence of

CCLK pulses, they all recognize length-count mat ch on the

same CCLK edge, as indicated on the left edge of

Figure 25. The master device then generates additional

CCLK pulses until it reaches its finish poin t F. The different

families generate or require different numbers of additional

CCLK pulses until they reach F. Not reach ing F means that

the device does not really finish its configuration, although

DONE may have gone High, the outputs became active,

and the internal reset was released. For the

XC5200-Series device, not reaching F means that read-

back cannot be initiated and most boundary scan instruc-

tions cannot be used.

The user has some control over the relative timing of these

events and c an, t here fore , make sure that they oc cur a t th e

proper t ime and the finish point F is reached . Timi ng is con-

trolled using options in the bitstr eam generati on software.

XC5200 devices always have the same number of CCLKs

in the power up delay, independent of the configuration

mode, un li ke the XC3 000/ XC400 0 Seri es d evice s. To guar-

antee all devices in a daisy chain have finished the

power-up delay, tie the INIT pins together, as shown in

Figure 27.

XC3000 Master with an XC520 0-Series Slave

Some designers want to use an XC3000 lead device in

peripheral mode and have the I/O pins of the

XC5200-Series devices all available for user I/O. Figure 22

provides a solution for that case.

This solution requires one CLB, one IOB and pin, and an

internal oscillator with a frequency of up to 5 MHz as a

clock source. The XC3000 master device must be config-

ured with late Internal Reset, which is the default option.

One CLB and one IOB in the lead XC3000-family device

are used to gener ate the addit ional CCLK pu lse require d by

the XC5200-Series devices. When the lead device

removes the internal RESET sig nal, the 2-bit shift register

responds to its clock input and generates an active Low

output signal for the duration of the subsequent clock

period. An external connection between this output and

CCLK thus creates the extra CCLK pulse.

Express Mode

Express mode is similar to Slave Serial mode, except the

data is presented in parallel format, and is clocked into the

targe t devi ce a byte at a ti me rath er than a bit at a time . The

data is loaded in parallel into eight different columns: it is

not internally serialized. Eight bits of configuration data are

loaded with every CCLK cycle, therefore this configuration

mode runs at eight times the data rate of the other six

modes . In this mo de the XC 5200 fa mily is capab le of sup-

porti ng a CCLK freque ncy of 10 MHz, w hich is equiv alent to

an 80 MHz serial rate, because eight bits of configuration

data are being loaded per CCLK cycl e. An XC5210 in the

Express mode, for instance, can be configured in about 2

ms. Th e Ex pr es s mode do es no t su pport C RC err or chec k -

ing, but does support constant-field error checking. A

length count is not used in Express mode.

In the Express configuration mode, an external signal

drives the CCLK input(s). The first byte of parallel configu-

ration data must be available at the D inputs of the FPGA

devices a shor t set -u p time be fore th e se co nd risin g C CL K

edge. Subsequent data bytes are clocked in on each con-

secutive rising CC LK edge. See Figure 38 on page 123.

Bitstream generation currently generates a bitstream suffi-

cien t to pro gram in all confi gurati on mode s except E xpress .

Extra CCLK cycles are necessary to complete the configu-

ration, since in this mode data is read at a rate of eight bits

per CCLK cycle instead of one bit per cycle. Normally the

entire start-up sequence requires a number of bits that is

equal to the number of CCLK cycles needed. An additional

five CCLKs (equivalent to 40 extra bits) will guarantee com-

pletion of configuration, regardless of the start-up options

chosen.

Multiple slave devices with identical configurations can be

wired with parallel D0-D7 inputs. In this way, multiple

devices can be configured simultaneously.

Pseudo Da isy Chai n

Multiple devices with different configurations can be con-

nected togethe r in a pseudo dai sy chain, provi ded that all of

the devices are in Express mode. A single combined bit-

stream is used to configure the chain of Express mode

devices, but the input data bus must drive D0-D7 of each

devic e. Tie High t he CS1 p in o f the firs t dev ice t o be c onfig-

ured, or lea ve it f loa tin g in the XC5200 sin ce it h as an inter-

nal pull-up. Connect the DOUT pin of each FPGA to the

CS1 pin of the next device in the chain. The D0-D7 inputs

are wired to each device in parallel. The DONE pins are

wired together, with one or more internal DONE pull-ups

activated. Alternatively, a 4.7 kΩ external resistor can be

used, if desired. (See Figure 37 on page 122.) CCLK pin s

are tied toge ther.

The requirement that all DONE pins in a daisy chain be

wired to ge th er app li es on l y to Exp ress mod e, an d o nly i f all

devices in the chain are to become active simultaneously.

All devices in Express mode are synchronized to the DONE

pin. User I/O for each device become active after the

DONE pin for that device goes High. (The exact timing is

determined by options to the bitstream generation soft-

ware.) Since the DONE pin is open-drain and does not

drive a High value, tying the DONE pins of all devices

together prevents all devices in the chain from going High

ration cycle.

Setting CCLK Frequency

For Mast er mod es , CCLK c an be gen er at ed in o ne o f th re e

frequencies. In the default slow mode, the frequency is

nominally 1 MHz. In fast CCLK mode, the frequency is

nominally 12 MHz. In medium CCLK mode, the frequency

is nomin al ly 6 MH z. The fr eq uen cy rang e i s -50% to + 50%.

The frequency is selected by an option when running the

bits trea m gener ation soft war e. If an XC5 200-Se ries Mast er

is driving an XC3000- or XC2000-family slave, slow CCLK

mode must be used. Slow mode is the default.

Data Stream Format

The data stream (“bitstream”) format is identical for all con-

figurat ion modes, with the exception of Expre ss mode. In

Express mode, the device becomes active when DONE

goes High, therefore no l ength count is required. Addition-

all y, CRC error check ing is not suppo rted in Expr ess mo de.

The data stream formats are shown in Table 11. Express

mode data is shown with D0 at the left and D7 at the right.

For all other modes, bit-serial data is read from le ft to right,

and byte-parallel data is effectively assembled from this

serial bitstream, with the first bit in each byte assigned to

D0.

The configuration data stream begins with a string of eight

ones, a preamble code, followed by a 24-bit length count

and a separator field of ones (or 24 fill bits, in Express

mode). This header is followed by the actual configuration

data in frames. The length and number of frames depends

on the devic e ty pe (see Table 12). Ea ch fr ame b egins with

a start field and ends with an error check. In all modes

except Express mode, a postamble code is required to sig-

nal the end of data for a single device. In all cases, addi-

tional start-up bytes of data are required to provide four

cloc ks for the startup sequence at the end of configuration.

Long daisy chains require additional startup bytes to shift

the last data through the chain. All startup bytes are

don’t-cares; these bytes are not included in bitstreams cre-

ated by the Xilinx software.

In Express mode, only non-CRC error checking is sup-

porte d. I n all o ther mo des , a se lec t ion of CRC or non -C RC

error checki ng is allowe d by the bit stream gener ation so ft-

ware. The non-CRC error checking tests for a designated

end-of -fr ame f ield for each fram e. For CRC err or c hecki ng,

the software calculates a running CRC and inserts a unique

four-bit partial check at the end of each frame. The 11-bit

CRC check of the last frame of an FPGA includes the last

seven data bits.

The user must de tect IN IT and initialize a new configuration

by puls ing th e PROGRAM pin Low or cycling Vcc.

Cyclic Redundancy Check (CRC) for

Configura tion an d Read back

The Cyclic Redundancy Check is a method of error detec-

tion in data transmission applications. Generally, the trans-

mitting system performs a calculation on the serial

bitstream. The result of this calculation is tagged onto the

data stream as additional check bits. The receiving system

perfor ms an id entic al ca lcu lati on on t he b itst ream and c om-

pares the result with the rec eived checksum.

Each data frame of the configuration bitstream has four

error bits at the end, as shown in Table 11. If a frame data

error is detected during the loading of the FPGA, the con-

figuration process with a potentially corrupted bitstream is

termi nated . The FPG A pull s the I NIT pin L ow and goe s int o

a Wait state.

Durin g Readba ck, 11 bits of the 16- bit chec ksum ar e added

to the end of the Readback data stream. The checksum is

computed using the CRC-16 CCITT polynomial, as shown

in Figure 23. The checksum consists of the 11 most signifi-

cant bi ts o f the 16-b it code. A change in the c heck sum indi -

cates a change in the Readback bitstream. A comparison

to a pre vious che cksum is mean ingful on ly if the rea dback

data is independent of the current device state. CLB out-

puts should not be included (Read Capture option not

used). Stat isti call y, on e err or out of 2048 migh t go un dete c-

Configuration Sequence

There ar e f ou r maj or s t eps in t he XC52 00-S er ies po wer- up

configuration sequence.

• Power-On Time-Out

• Initialization

• Configuration

• Start-Up

The full process is illustrated in Figure 24.

Power-On Time-Out

An internal power-on reset circuit is triggered when power

is ap pli ed . When VCC reaches the voltage at which portions

of the FPGA begin to operate (i.e., performs a

write-and-read test of a sample pair of configuration mem-

ory bits), the programmable I/O buffers are 3-stated with

active high-impedance pull-up resistors. A time-out delay

— nom inally 4 ms — is initia ted to allow the p ower-supply

voltage to stabilize. For correct operation the power supply

must reach VCC(min) by the end of the time-out, and must

not dip below it thereafter.

There is no distinction between master and slave modes

with regard to the time-out delay. Instead, the INIT line is

used to ensure that all daisy-chained devices have com-

plet ed in itia liz ation. Sinc e XC20 00 dev ices do not have this

signal, extra care must be taken to guarantee proper oper-

ation when daisy-chaining them with XC5200 devices. For

proper operation with XC3000 devices, the RESET sign al,

which is used in XC3000 to delay configuration, should be

connected to INIT.

If the time -out d elay is ins ufficient, co nfigu rat ion sho uld be

delayed by holding the INIT pin Low until the power supply

has reached op e ra tin g leve ls.

This delay is applied only on power-up. It is not applied

when reconfiguring an FPGA by pulsing the PROGRAM

pin Lo w. During all th ree ph ases — P ower- on, I nit ializ ation ,

and Configuration — DONE is held Low; HDC, LDC, and

INIT are active; DOUT is driven; and all I/O buffers are dis-

abled.

Initialization

This phase clears the configuration memory and estab-

lishes the configuration mode.

The configuration memory is cleared at the rate of one

frame per internal clock cycle (nominally 1 MHz). An

open-drain bidirectional signal, INIT, is released when the

configuration memory is completely cleared. The device

then tests for the abse nce of an extern al active -low lev el on

INIT. The mode lines are sampled two internal clock cycles

later (nominally 2 µs).

The master device waits an additional 32 µs to 256 µs

(nominally 64-128 µs) to provid e adequ ate t ime f or all of t he

slav e devices to r ecognize th e release of IN IT as well. Then

the ma ster device enters the Configuration phase.

Configuration

The l ength cou nter b egins c ounti ng immedi ately upon entr y

into the configuration state. In slave-mode operation it is

important to wait at least two cycles of the internal 1-MHz

clock oscillator after INIT is recognized before toggling

CCLK and feeding the serial bitstream. Configuration will

not begin until the internal configuration logic reset is

released, which happens two cycles after INIT goes High.

A master device’s configuration is delayed from 32 to 256

µs to ens ure prop er operation with any s lave devic es driven

by the master devic e.

The 0010 preamble code, included for all modes except

Express mode, indicates that the following 24 bits repre-

sent t he len gt h c ount . Th e le ngt h c ou nt i s the t ot al nu mbe r

of co nf i gu ra tio n c l o cks ne ed ed to lo ad t he co mple te c on fig -

uration data. (Four additional configuration clocks are

required to complete the configuration process, as dis-

cussed below.) After the preamble and the length count

have be en pas sed t hrou gh to all de vice s in t he dai sy ch ain ,

DOUT is held High to prevent frame start bits from reaching

any daisy-chained devices. In Express mode, the length

count bits are ignored, and DOUT is held Low, to disable

the ne xt device in the pseudo daisy chain.

A spe cifi c conf igu rati on b it, ea rly i n th e fi rst fr ame of a mas -

ter device, controls the configuration-clock rate and can

increase it by a factor of eight. Therefore, if a fast configu-

ration clock is selected by the bitstream, the slower clock

rate is used until this configuration bit i s detected.

Each frame has a start field followed by the frame-configu-

rati on da ta b its a nd a frame err or f ield. If a f rame data erro r

is detected, the FPGA halts loading, and signals the error

by pullin g the open -drain INIT pin Low. After all configura-

tion frames have been loaded into an FPGA, DOUT again

follows the input data so that the remaining data is passed

on to the next device. In Express mode, when the first

device is fully programmed, DOUT goes High to enable the

next device in the chain.

Delaying Configuration After Power-Up

To delay master mode configuration after power-up, pull

the bidirectional INIT pin Low, using an open-collector

(open-drain) driver. (See Figure 12.)

Using an open-collector or open-drain driver to hold INIT

Low before the beginning of master mode configuration

causes the FPGA to wait after completing the configuration

memory clear operation. When INIT is no longer he ld Low

externally, t he device det ermines its configurat ion mod e by

captu ri ng i ts mod e pins , and is rea dy to st ar t t he conf i gura -

tion proces s. A maste r device waits up to an addi tional 250

µs to make sure that any slaves in the optional da isy chain

have seen that INIT is High.

Start-Up

Start-up is the transition from the configuration process to

the intended user operation. This transition involves a

change from one clock source to another, and a change

from interfacing parallel or serial configuration data where

most ou tputs are 3-sta ted, t o normal op erati on with I/O pins

active in the user-system. Start-up must make sure that

the user-logic ‘wakes up’ gracefully, that the outputs

beco me ac t i ve w i tho ut c au sin g c ont en tio n w ith t he c onf i gu-

ration signals, and that the internal flip-flops are released

from the global Reset at the right time.

Figure 25 describes start-up timing for the three Xilinx fam-

ilies in detail. Express mode configuration always uses

either CCLK_SYNC or UCLK_SYNC timing, the other con-

figur ation modes can use any of t he f our ti ming se quenc es.

To acce ss the i nterna l start- up signal s, place the STARTUP

library symbol.

Start-up Timing

Different F PGA fa milie s ha ve different star t-u p seq uenc es .

The XC200 0 fami ly g oes t hrou gh a fi xed sequenc e. D ONE

goes H igh and the i ntern al g lobal Reset is de -act ivat ed on e

CCLK period after the I/O become active.

The XC3 000A family offers some flexibility. DONE can be

programmed to go High one CCLK period before or after

the I/O beco m e active. Independent of DONE, the inte rnal

global Reset is de-activated one CCLK period before or

after the I/O become active.

The XC4000/XC5200 Series offers additional flexibility.

The three ev ents — DO NE going High, the in ternal Re set

being de-ac tivated, and the user I/O going active — can all

occur in any arbitrary sequence. Each of them can occur

one CCLK pe ri od be fo re or af t er, or simultan eou s w it h, any

of the others. This relative timing is selected by means of

software options in the bitstream generation software.

The default option, and the most practical one, is for DONE

to go Hig h first, disconnec ting the conf igurati on data sour ce

and avoiding any contention when the I/Os become active

one cl ock l ater. Reset is then releas ed an othe r cloc k peri od

later to make sure that user-operation starts from stable

internal conditions. This is the most common sequence,

shown with heavy lines in Figure 25, but the designer can

modify it to meet particular requirement s.

Normal ly, the start -up se quence is cont rolled by the inte rnal

device oscillator output (CCLK), which is asynchronous to

the system clock.

XC4000/XC5200 Series offers another start-up clocking

option, UCLK_NOSYNC. The three events described

above ne ed not be trigger ed by CCLK . They can , as a con-

figuration option, be tri ggered by a user c lock. This means

that the device can wake up in synchronism with the user

system .

Product Obsolete or Under Obsolescence

November 5, 1998 (Version 5.2) 7-111

XC5200 Series Field Programmable Gate Arra ys

When the UCLK_SYNC option is enabled, the user can

externally hold the open-drain DONE output Low, and thu s

stall all further progress in the start-up sequence until

DONE is r eleased and h as go ne Hig h. This op tion ca n be

used to forc e synchr onizatio n of se veral FP GAs to a com-

mon user clock, or to guarantee that all devices are suc-

cessfully configured before any I/Os go active.

If either of these two op tions is selected, and no user clock

is sp ecifi ed in the d esign or att ache d to th e devic e, th e chip

coul d r each a po i nt w her e t he conf i gu rati o n o f th e de v ice i s

complete and the Done pin is asserted, but the outputs do

not become active. The solution is either to recreate the

bitstream specifying the start-up clock as CCLK, or to sup-

ply the appropriate use r clock.

Start-up Sequence

The Start-up sequence begins when the configuration

memor y i s fu l l , and t he to ta l nu mber o f co nf i gu ra tio n c loc k s

received since INIT went High equals the loaded value of

the lengt h co un t.

The next rising clock edge sets a flip-flop Q0, shown in

Figure 26. Q0 is the leading bit of a 5-bit shift register. The

outputs of th is register can be programmed to control three

events.

• The release of the open-drain DONE output

• The cha nge of configurati o n-relate d pins to the user

function, activating all IOBs.

• The ter minat ion of the globa l Set/R eset initialization of

all CLB and IOB storage elements.

The DONE pin can al so be w ire- A NDe d wit h DON E pins of

other FPGAs or with other external signals, and can then

be used as input to bit Q3 of the start-up register. This is

called “Start-up Timing Synchronous to Done In” and is

selecte d by either CCL K_SYNC or UCLK_SYNC.

When D ONE is not u sed as an i nput, the operati on is ca lled

“Start-up Timing Not Synchronous to DONE In,” and is

selecte d by either CCL K_NO SYNC or UCLK _NO SYNC.

As a configuration option, the start-up control register

beyond Q0 can be clocked either by subsequent CCLK

pulses or from an on-chip user net called STARTUP.CLK.

These signals can be accessed by placing the STARTUP

library symb ol.

Start-up from CCLK

If CCLK is used to drive the start-up, Q0 through Q3 pro-

vide the timing. Heavy lines in Figure 25 show the default

timing, which is compatible with XC2000 and XC3000

devices using early DONE and late Reset. The thin lines

indicate all other poss ible timing options.

Start -up from a User Clock (STARTUP.CLK)

When, instead of CCLK, a user-supplied start-up clock is

sele ct ed , Q1 is us ed to br i dg e t he un k nown pha se r el at ion -

ship between CCLK and the user clock. This arbitration

causes an unavoidable one-cycle uncertainty in the timing

of the rest of the start-up sequence.

DONE Goes High to Signal End of Configuration

In all configuration modes except Express mode,

XC5200-Series devices read the expected length count

from the bitstream and store it in an internal register. The

lengt h cou nt var ies accord ing to t he num ber of d evi ces an d

the composition of the daisy chain. Each device also

coun ts the number of CCLKs during configuration.

Two conditions have to be met in order for the DONE pin to

go high:

• the chi p's internal memory must be full, and

• the configuration length count must be met,

exactly

This is important because the counter that determines

when the length count is met begins with the very first

CCLK, not the first one after the preamble.

Therefore, if a stray bit is inserted before the preamble, or

the data source is not ready at the time of the first CCLK,

the internal counter that holds the number of CCLKs will be

one ahead of the actual number of data bits read. At the

end o f configuratio n, the config uration mem ory will be fu ll,

but the number of bits in the internal counter will not match

the expected length count.

As a c onsequence, a M aster mode device will contin ue to

send out CCLKs until the internal counter turns over to

zero, and then reaches the correct length count a second

time. This will tak e several secon ds [224 ∗ CC LK period]

— whic h is some times inte rpret ed as the devi ce not c onfi g-

uring at all.

If it is not possible to have the data ready at the time of the

first CCLK, the problem can be avoided by increasing the

number in the length count by the appropriate value.

In Ex pr es s m od e , th er e is no le ng th co un t. T h e DON E pin

for e ach devic e goes Hig h when th e devic e has rec eived i ts

quota of configuration data. Wiring the DONE pins of sev-

eral devices together delays start-up of all devices until all

are fully configured.

Note that DONE is an open-drain output and does not go

High unless an internal pull-up is activated or an external

pull-up is attached. The internal pull-up is activated as the

default by the bitstream generation software.

Release of User I/O After DONE Goes High

By de fa ult , th e us er I/O a re re le as ed on e CCL K cy cle af te r

DONE goes High, the outputs remain in their initial state —

controlled by an option to the bitstream generation soft-

ware.

Three full CCLK cycles are required after the DONE pin

goes H igh, as sh own in Figure 25 on page 109. If CCLK is

not clocked three times after DONE goes High, readback

Note that in XC5200-Series devices, configuration data is

not

inverted wit h respect to configuration as it is in XC2000

and XC3000 families.

Readb ack of Ex press mod e bitstr eams re sults in data that

does not resemble the original bitstream, because the bit-

stream for m at differ s fro m othe r mod es .

XC5200-Series Readback does not use any dedicated

pins, but uses four internal nets (RDBK.TRIG,

RDBK.DATA, RDBK.RIP and RDBK.CLK) that can be

routed to any IOB. To access the internal Readback sig-

nals, place the READBACK library symbol and attach the

appro pri at e pa d sym b ols , as sh own in Figure 27.

After Readback has been initiated by a Low-to-High transi-

tion on RDBK.TRIG, the RDBK.RIP (Read In Progress)

output goes High on the next rising edge of RDBK.CLK.

Subsequent rising edges of this clock shift out Readback

data on the RDBK.DATA net.

Readback data does not include the preamble, but starts

with five dummy bits (all High) followed by the Start bit

(Low) of the first frame. The first two data bits of the first

frame are always Hig h.

Each f ra m e e n ds w i th fo ur er ro r che ck bits. Th ey are r ea d

read back as High. An additional Start bit (Low) and an

11-bit Cyclic Redundancy Check (CRC) signature follow,

before RDBK.RIP returns Low.

Readback Op tion s

Readback options are: Read Capture, Read Abort, and

Clock Select. They are set with the bitstream generation

software.

Read Capture

When the Read Capture option is selected, the readback

data stream includes sampled values of CLB and IOB sig-

nals. The rising edge of RDBK.TRIG latches the inverted

valu es of th e CLB o utputs a nd the IOB ou tput a nd input sig-

nals. Note that while the bits describing configuration

(int erco nnec t and func tion g enera tors ) are

not

inve rted, t he

CLB and IOB output signals

are

inverte d.

When th e Read Captur e option is n ot sele cted, th e values

of the capture bits reflect the configuration data originally

written to those memory locations.

The readback signals are located in the lower-left corner of

the de vice .

Read Abort

When the Read Abort option is selected, a High-to-Low

transition on RDBK.TRIG terminates the readback opera-

tion and prep ares the logic to accept another trigger.

After an aborted readback, additional clocks (up to one

readbac k c lock per co nfi gura tion f rame ) may be r equir ed t o

re-in itial ize the cont rol logic . The status of rea dback is i ndi-

cated by the output control net RDBK.RIP. RDBK.RIP is

High whenever a readback is in progress.

Clock Select

CCLK is the default clock. However, the user can insert

another clock on RDBK.CLK. Readback control and data

are clocked on rising edges of RDBK.CLK. If readback

must be in hibite d for secu rity reasons, the readb ack contr ol

nets are simply not connected.

Violating the Maximum High and Low Time

Specification for the Readba ck Clock

The readback clock has a maximum High and Low time

specification. In some cases, t his specification cannot be

met. For example, if a processor is controlling readback,

an inte rrupt may force it to stop in th e middle of a readbac k.

This necessitates stopping the clock, and thus violating the

specification.

The sp ecification is mandatory only on clocking data at the

end of a frame prior to the next start bit. The transfer mech-

anism will load the data to a shift register during the last six

clock cycles of the frame, prior to the start bit of the follow-

ing frame. This loading process is dynamic, and is the

sourc e of th e ma xim u m High and Low tim e re qu ir em e nt s.

Therefore, the specification only applies to the six clock

cycles prior to and including any start bit, including the

clocks before the first start bit in the readback data stream.

At othe r ti mes , the fra me da ta is al re ady i n th e re gis te r an d

the register is not dynamic. Thus, it can be shifted out just

like a regula r shift register.

The us er must p recisely calcu late the lo cation of the read-

back data relative to the frame. The system must keep

track of the position within a data frame, and disable inter-

rupts before frame boundar ies. Fr ame le ngths an d data for-

mats ar e liste d in Table 11 and Table 12.

Readback with the XChe cker Cable

The XChecker Universal Download/Readback Cable and

cation. It can also display selected internal signals on the

Configuration Timing

The seven configuration modes are discussed in detail in

this section. Timing specifications are included.

Slave Serial Mode

In Slave Serial mode, an external signal drives the CCLK

input of th e FPGA . T he ser i al co nf i gu ra tio n bi t str eam mus t

be available at the DIN input of the lead FPGA a short

setup time before each rising CCLK edge.

The lead FPGA then presents the preamble data—and all

data that overflows the lead device—on its DOUT pin.

There is an internal delay of 0.5 CCLK periods, which

mean s th at D OUT ch an g es o n th e fa llin g CC LK e dg e, and

the next FPGA in the daisy chain accepts data on the sub-

sequ ent rising CCLK edge.

Figure 28 shows a full master/slave system. An

XC5200-Series device in Slave Serial mode should be con-

necte d as sh ow n in the thir d de vice fro m the lef t.

Slave S erial mode is sel ected b y a <111> on the mo de pins

(M2, M1, M0). Slave Ser ial is the defau lt mode if the mode

Master Serial Mode

In Master Serial mode, the CCLK output of the lead FPGA

drives a Xilinx Serial PROM that feeds the FPGA DIN input.

Each rising edge o f the CCLK output increments the Serial

PROM int ernal address coun ter. The next data bit is put on

the SPR OM data o utput, co nnected t o the FP GA DIN pin.

The lead FPGA accepts this data on the subsequent rising

CCLK edge.

The lead FPGA then presents the preamble data—and all

data that overflows the lead device—on its DOUT pin.

There is an internal pipeline delay of 1.5 CCLK periods,

which means that DOUT changes on the falling CCLK

edge, and th e next FPGA in the daisy chain accepts da ta

on the subsequent rising CCLK edge.

In the bitstream generation software, the user can specify

Fast ConfigRate, which, starting several bits into the first

fra me, inc reas es th e CCLK f reque ncy b y a facto r of tw elve .

The val ue incr eases fr om a nomi nal 1 MH z, to a nominal 12

MHz. Be sure that the serial PROM and slaves are fast

enough to support this data rate. The Medium ConfigRate

option changes the frequency to a nominal 6 MHz.

XC2000, XC3000/A, and XC3100A devices do not support

the Fast or Medium ConfigRate options.

The SPROM CE input can be driven from either LDC or

DONE . Us ing LDC avoids potential contention on the DIN

pin, if this pin is configured as user-I/O, but LDC is then

restricted to be a permanently High user output after con-

figuration. Using DONE can also avoid contention on DIN,

provided th e DONE before I/O enable option is invoked.

Figure 28 on page 114 shows a full master/slave system.

The leftmost device is in Master Serial mode.

Master Serial mode is selected by a <000> on the mode

pins (M2, M1, M0).

Notes: 1. At power-up, V cc mus t rise from 2.0 V to Vcc m i n in less th an 25 ms, otherwise delay confi guration by pul l i ng P ROGRAM

Low until Vcc is valid.

2. Master Serial mode timing is based on testing in slave mode.

Figure 30: Master Serial Mode Programming Switching Characteristics

In the two Master Parallel modes, the lead FPGA directly

addresses an industry-standard byte-wide EPROM, and

accepts eight data bits just before incrementing or decre-

menting the address outputs.

The eight data bits are serialized in the lead FPGA, which

then presents the preamble data—and all data that over-

flows the le ad device—on its DO UT pin . Th er e is an in ter-

nal delay of 1.5 CCLK periods, after the rising CCLK edge

that accepts a byte of data (and also changes the EPROM

address) until the falling CCLK edge that makes the LSB

(D0) of this byte appear at DOUT. This means that DOUT

changes on the falling CCLK edge, and the next FPGA in

the daisy chain accepts data on the subsequent rising

CCLK edge.

The PROM address pins can be incremented or decre-

mented, depending on the mode pin settings. This option

allows th e FP GA to sh ar e th e PROM with a wid e va rie ty of

microprocessors and microcontrollers. Some processors

must boot fro m the bottom of memory (al l zeros) whil e oth-

ers must boot from the top. The FPGA is flexible and can

load i ts confi gurat io n bits trea m fro m eithe r end of t he mem-

ory.

Master Parallel Up mode is selected by a <100> on the

mode pins (M2, M1, M0). The EPROM addresses start at

00000 and increment.

Master Pa rallel Down mo de is selected by a <110> on the

mode pins. The EPROM addresses start at 3FFFF and

decrement.

Synchronous Peripheral Mode

Synchronous Peripheral mode can also be considered

Slave Parallel mode. An external signal drives the CCLK

input (s) of th e FPGA (s). The f irst byte o f par alle l conf ig ura-

tion data must be available at the Data inputs of the lead

FPGA a short setup time before the rising CCLK edge.

Subsequent data by tes are clock e d in on every eighth con-

secutive rising CCLK edge.

The same CCLK edge that accepts data, also causes the

RDY/BUSY output to go High for one CCLK period. The pin

name is a mis no m er. In Synchron ou s Pe rip h er al m od e it is

really an ACKNOWLEDGE signal. Synchronous operation

does n ot re quir e t his r es pon se, but it i s a me an i ngful s ig nal

for test purposes. Note that RDY/BUSY is pulled Hig h with

a high-impedance pullup pr ior to INIT going High .

The lead FPGA serializes the data and presents the pre-

amble data (and all data t hat overflow s the lead device) on

its DOUT pin . Th er e is an int erna l d elay o f 1 .5 CCLK pe r i-

ods, which means that DOUT changes on the falling CCLK

edge, and the next FPGA in the daisy chain accepts data

on the subsequent rising CCLK edge.

In order to complet e the serial shift operation, 10 additional

CCLK rising edges are required after the last data byte has

been loaded, plus one more CCLK cycle for each

daisy-chained de vice.

Synchronous Peripheral mode is selected by a <011> on

the mode pins (M2, M1, M0).

Notes: 1. Peripheral S ynchronous mod e can be considered Slave Par al l el mo de. An external CCLK provides timing, cl ocking in the

first data byte on the second ris i ng edge of CCLK after INIT goes high. Sub sequent data bytes are cloc ked in on every

eighth co nsecutive rising edge of CCLK.

2. The RDY/BUSY l ine goes High f or one CCLK period after data has been clock ed i n, although sy nchronous operation does

not require such a respons e.

3. The pin name RDY/BUS Y is a misnomer. In synchro nous peripheral m ode this is really an ACKNOWLE DGE signal.

Asynchro no us Perip her al Mod e

Write to FPGA

Asynchronous Peripheral mode uses the trailing edge of

the logic AND condition of WS and CS0 be i ng Lo w and RS

and CS1 being High to accept byte-wide data from a micro-

proce ss or bu s. In t he l ead FPGA, t hi s d at a i s loa de d i n to a

double-buffered UART-like parallel-to-serial converter and

is serially shifted into the internal logic.

The lead FPGA presents the preamble data (and all data

that overflows the lead device) on its DOUT pin. The

RDY/BUSY output from the lead FPGA acts as a hand-

shake sig nal to the microprocessor. RDY/BUSY goes Low

when a byt e has been rec eive d, and goes Hig h again wh en

the byte-wide input buffer has transferred its information

into the shift register , and the buffer is ready to receive new

data. A new write may be started immediately, as soon as

the RDY/BUSY output has gone Low, acknowledging

receipt of the prev ious data. Write m ay not be te rminated

until RDY/BUSY is H igh a gain for o ne CC LK peri od. Note

that RDY/BUSY is pulled High with a high-impedance

pull-up prior to INIT going High.

The length of the BUSY signal depends on the activity in

the UART. If the shift register was empty when the new

byte was received, the BUSY signal lasts for only two

CCLK periods. If the shift register was still full when the

new byte was rec e ived , the BUSY sign al c an b e a s lo ng a s

nine CCLK pe rio d s.

Note that after the last byte has been entered, only seven

of its bits ar e shifted out. CCLK r emains High with DOUT

equal t o bit 6 (the next-t o-last bit) of the last byte ente red.

The READY/BUSY handshake can be ignored if the delay

from any one Write to the end of the next Write is guaran-

teed to be longer tha n 10 CCLK periods.

Status Read

The logic AND condition of the CS0, CS1 and RS inputs

puts the device status on the Data bus.

• D7 High indicat es Ready

• D7 Low in dicate s Busy

• D0 through D6 go unconditional ly High

It is ma nd at or y th at t he wh ole st a rt -u p s eq uenc e b e s t art e d

and completed by one b yte-wide input. Otherwise, the pins

used as Write Strobe or Chip Enable might become active

outputs and interfere with the final byte transfer. If this

transfer does not occur, the start-up sequence is not com-

pleted all the way to the finish (point F in Figur e 25 on pag e

109).

In this ca se, at worst, the inte rnal reset is no t released. A t

best, Readback and Boundary Scan are inhibited. The

length-count value, as generated by the software, ensures

that these problems never occur.

Although RDY/BUSY is brought out as a separate signal,

microprocessors can more easily read this information on

one of the data lines. For this purpose, D7 represents the

RDY/BUSY status when RS is Low, WS is High, and the

two chip select lines are both active.

Asynchronous Peripheral mode is selected by a <101> on

the mode pins (M2, M1, M0).

Notes: 1. Configuration must be del ayed until INIT pins of all dai sy-chai ned FPGAs are high.

2. The time from the end of WS to CCLK cycle for the new byte of data depends on the completion of previous byte processing

and the phase of internal timing generator for CCLK.

3. CCLK and DOUT timing is tested in sla ve m ode.

4. TBUSY indicates that the double-buffered parallel-to-serial converter is not yet ready to receive new data. The shortest TBUSY

occurs when a byte is loaded i nto an empty parallel-to-serial converter. The longes t TBUSY occurs when a new word is

loaded into t he i nput register before the second-l evel buffer has started shift i ng out data.

Express Mod e

Expre ss mo de is sim ilar to S lave Seria l mode, except that

data is processed one byte per CCLK cycle instead of one

bit per CCLK cycle. An external source is used to drive

CCLK, wh ile b yt e-wid e d a ta is lo ade d d ir ect ly in to th e co n-

figuration data shift registers. A CCLK frequency of 10

MHz is equivalent to an 80 MHz serial rate, because eight

bits of configuration data are loaded per CCLK cycle.

Express mode does not support CRC error checking, but

does support constant-field error checking.

In Ex press mode, an external signal drives the CCLK input

of the FPGA device. The first byte of parallel configuration

data must be available at the D inputs of the FPGA a short

setup time before the second rising CCLK edge. Subse-

quen t data bytes are clocked in on each consecutive rising

CCLK edge.

If the first device is configured in Express mode, additional

devices may be daisy-chained only if every device in the

chain is also con figured in Expres s mode . CCLK p ins are

tied together and D0-D7 pins are tied together for all

devices along the chain. A status signal is passed from

DOUT to CS1 of successive devices along the chain. The

lead de vice in the chai n has its CS1 i nput tied High (o r float-

ing, since there is an internal pullup). Frame data is

accept ed on ly when CS1 is Hig h and the devic e’s config u-

ration memory is not already full. The status pin DOUT is

pulled Low two internal-oscillator cycles after INIT is r ec og-

nized as High, and remains Low until the device’s configu-

ration memory is full. DOUT is then pulled High to signal

the nex t devi ce in t he chai n to a ccept t he conf igurati on dat a

on the D0-D7 bus.

The DONE pins of all devices in the chain should be tied

together, with one or more active internal pull-ups. If a

large number of devices are included in the chain, deacti-

vate some of the internal pull-ups, since the Low-driving

DONE pin of the last device in the chain must sink the cur-

rent from all pull-ups in the chain. The DONE pull-up is

activated by default. It can be deactivated using an option

in the bitstr eam generation software.

XC5200 devices in Express mode are always synchronized

to DONE. The device becomes active after DONE goes

High. DONE is an open-drain output. With the DONE pins

tied t ogether , theref ore, the ex ternal DONE signal st ays low

until all dev ices are c onf igured , th en al l devic es in the daisy

chain become active simultaneously. If the DONE pin of a

device is left unconnected, the device becomes active as

soon as that device has been configured.

Express mode is selected by a <010> on the mode pins

(M2, M1, M0).
