1.5i Virtex Map - Not all instances a timespec are being covered by the resulting .pcf file.


Keywords: bus, bit, slice, timespec, map

Urgency: Standard

General Description:
Not all instances covered by a timespec are being covered by the resulting .pcf file.


The 1_5 mapper has a bug when packing FDCP or FDRS type flops. The
tspecs are not properly transferred. A workaround is to prevent any packing
around FDCP or FDRS flops by applying XBLKNM attributes to the instances

INST "inst_name" XBLKNM=unique_string" ;

This problem has been fixed in the 2.1i release, due to begin shipping in June.
