Problem Title:
LogiCORE PCI64 Virtex (v3.0): Some timespecs have zero items analyzed in the TRCE report


Problem Description:
Urgency: Standard

General Description:

The TRCE timing report seems to have some timespecs with zero
analyzed items when the 64-bit/33MHz version of the LogiCORE
is compiled in 1.5is2 software


Solution 1:

There are two reasons for this

1. Some paths, e.g. FFS to PAD, are not reported if the path is
entirely in the IOB.

2. Some timespecs are valid only for the 64-bit/66MHz version
of the core and listed in the UCF file to make it complete.
