AR# 10873: 3.1i Virtex-II PAR - Design with Block RAM has unplaceable components.
3.1i Virtex-II PAR - Design with Block RAM has unplaceable components.
Keywords: BLKRAM, BlockRAM, macro, place, placer
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.
