3.1i Virtex-II MAP - Packer changed to prevent DP/SP RAM combination in a Virtex-II slice.
説明
Keywords: DP RAM, SP RAM, combined, 16x1
Urgency: Standard
General Description: The packer has been changed to make the combination of a 16x1 SP RAM and the dual-port half of a 16x1DP RAM in the same slice illegal. (This had been causing placer errors, and was only useful when the SP is really half of a RAM16x2S; in this case, a 16x2 symbol should be used.)
