9.1i Constraints Editor/Floorplan Editor Virtex-4/-5 - Duplicate constraints are created after I import a different UCF, and system hangs on prohibits


When I perform File -> Import UCF, duplicate constraints are received, or the system hangs if there are prohibits in the UCF.


Make sure that you import specific constraints only once. The system does not check for duplicate constraints.

This is scheduled to be fixed in the next major release of the design tools.
