Problem Title:
2.1i Virtex Map - FDRSE optimized to zero incorrectly.
Problem Description:
Urgency: Standard
General Description:
A case has been seen where an FDRSE was incorrectly optimized to a constant. The D-input
was driven by GND, but because there was a signal on the SET pin, the optimization was not
correct. The optimization led to the trimming of an OBUFT bus because the enable pins were
constantly inactive.
Solution 1:
This problem is scheduled to be fixed in the next (as yet unnamed)
release following version 2.1i. This release is currently scheduled
for March, 2000.
