Is there any issue with DDR SDRAM, DDR2 SDRAM and DDR3 SDRAM High Performance Controller or High Performance Controller II in Arria II GX devices which may cause hardware failure?

Description

The fitter algorithm of the Quartus® II software version 10.1 and 10.0 places the resynchronization registers in the core logic instead of the dedicated I/O element in the periphery in Arria® II GX device, causing possible intermittent data corruption on the last word in a burst. There will be no timing violations in the design since Postamble Analysis is not reported by Quartus II software static timing analysis.

This issue will be fixed in a future version of the Quartus II software. For Quartus II version 10.1 and 10.0 SP1, the workaround is to install the Quartus II software patch and recompile your design.
