Quartus II Software Version 9.1 SP2 Device Support Release Notes March 2010 Altera Corporation
Stratix II devices fail to configure with EPCS devices
Stratix II devices failed to configure properly vwith EPCS devices due to incorrect
configuration length count used by the Quartus II 9.1 SP1 software. This issue is fixed
in the Quartus II 9.1 SP2 software. To correct the problem, regenerate the
programming file (.pof, .rbf) with the Quartus II 9.1 SP2 software or later. The .sof file
is not affected.
Applies to: Stratix II devices
Cyclone IV GX devices enforce incorrect data rate
The Quartus II software version 9.1 SP1 enforces the incorrect transceiver data rate
limits for Cyclone IV GX devices with C8 speed grade packages and all F324 or
smaller packages. This issue is fixed in the Quartus II 9.1 SP2 software.
Applies to: Cyclone IV GX devices
VCCIO pin count incorrect with device migration turned ON
When you migrate from a Stratix IV to a HardCopy IV or HardCopy IV GX device, if a
pin is NC in the Stratix IV device and VCCIO in either HardCopy device, the
migration result is NC. The correct migration result should be VCCIO, when the
referred I/O bank is available in all devices of the current migration chain.
Applies to: HardCopy IV and HardCopy IV GX devices
Arria II GX and Stratix IV GX require regenerating transceiver reconfiguration Memory
Initialization File
When the transceiver channel and PLL dynamic reconfiguration is enabled, and the
transceiver bonding mode is X4 or X8, the TX clock (coreclkout) is inactive after
reconfiguration. You must regenerate the transceiver reconfiguration Memory
Initialization File (.mif) with the Quartus II software version 9.1 SP1.
Applies to: Arria II GX and Stratix IV GX devices
Arria II GX designs require recompilation
The Quartus II software versions 9.1 and earlier can produce functional failures in
Arria II GX designs due to race conditions in the secondary signal region of RAM.
This possible malfunction is fixed in Quartus II software version 9.1 SP1, and requires
that you recompile your design.
Applies to: Arria II GX devices
No vertical migration for Engineering Sample Stratix IV 230 GX and E and 530 GX and E
Stratix IV 230 GX and E and 530 GX and E devices in Engineering Sample version are
not allowed for vertical migration with the production devices due to the voltage
changes. (Core voltage for ES devices is 0.95V, while core voltage for production
devices is 0.9V.). To access vertical migration, use the corresponding production
device in the design.
Applies to: Stratix IV devices
