Problem Title:
1.5i Map - A case has been seen where -pr b option drops an inversion between flop and BUFT.
Problem Description:
Urgency: standard
General Description:
If a Virtex design has a flip flop connected to an inverter and the output of the inverter enables a
BUFT, the design is mapped with the correct logic. When the -pr b option is used to push the flop i
nto the IOB, the inveris lost, corrupting the logic.
Solution 1:
This problem has been corrected for version 2.1i.
