3.1i Virtex MAP - Combined BLKRAM and slice-based area-groups are not translated correctly to PCF.


Keywords: Area Groups, BLKRAM, slice, PCF, UCF, translate

Urgency: Standard

General Description:
It has been discovered that MAP cannot simultaneously process area groups that
are both BLKRAM-based and slice-based. When the UCF file defines AREA
GROUPs for both slices and BLKRAMS, with associated range constraints, the PCF
produced by MAP only has the COMPGRP of elements defined *first* in the UCF, with
the second group missing.


A workaround is to map the design twice with each of the two area group types, then
combine the resulting PCF files.

This problem is fixed in the latest 3.1i Service Pack available at: The first
service pack containing the fix is 3.1i Service Pack 6.
