Description
Keywords: Phase, 4.2, PAR
My design is crashing during Placement Phase 4.2.
Are there any known issues to explain this failure?
Solution
There is a known issue where the clock placer (Phase 4.2) crashes if there is a BUFG in the design that is loadless.This problem will be fixed in ISE version 11.2. Meanwhile, either remove the loadless BUFG, or ensure that the BUFG has loads.
