11.1 Spartan-3A Place - Known Issue where Phase 4.2 crashes due to loadless clock buffer

描述

My design is crashing during Placement Phase 4.2.  

 

Are there any known issues to explain this failure?

解决方案

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.
