General Description: A case has been seen where PAR fails during the assembly stage with the error:
FATAL_ERROR:Route:basrtsanity.c:141:1.7 - Process will terminate. To resolve this error, please consult the Answers Database and other online resources at http://support.xilinx.com
It was discovered that when PAR is guiding from multiple modules, the guide code does not appear to check to see if a target net is routed before instantiating the guided route.

This problem will be fixed in the first 3.1i quarterly release, currently scheduled for August, 2000.
