3.1i Virtex-II PAR - Design with Block RAM has unplaceable components.


Keywords: BLKRAM, BlockRAM, macro, place, placer

Urgency: Standard

General Description:
It has been found that the placer was assembling macros from related BlockRAM components
incorrectly. Because the distance between two Block RAMs columns is not regular in Virtex-II,
creating macros without limiting the size will create placement problems.


This problem is fixed in the latest 3.1i Service Pack available at:
http://support.xilinx.com/support/techsup/sw_updates. The first
service pack containing the fix is 3.1i Service Pack 7.
