4.1i Virtex-II MAP - Multiple RAM16X1D components are not packed into slices as 16x2 DPRAMs

描述

Keywords: RAM16X1D, DPRAM, combined, slice

Urgency: Standard

General Description:
A change in the 4.1i software release has caused RAM16X1D components to no longer be combined into slices, which results in less efficient slice utilization.

(The problem occurs because of a change wherein high fanout nets are no longer used as a basis for related merging. An exception needs to be made for RAM components.)

解决方案

This problem is fixed in the latest 4.2i Service Pack, available at:

The first service pack containing the fix is 4.2i Service Pack 1.
