NOTE This Answer Record only applies to Virtex and Spartan-IIE or earlier architectures.
I am trying to map a partially completed design into a Virtex device, but MAP crashes as follows:
"Release 8.2i - Map I.31
Copyright (c) 1995-2006 Xilinx, Inc. All rights reserved.
Using target part "2s150pq208-5".
Mapping design into LUTs...
Segmentation fault (core dumped)"
In some cases, MAP crashes while processing a design that contains a BUFG with no input or output connections. This bug is being considered for a fix in a future design tool release. Until there is a fix, make sure that any unconnected BUFGs are removed from the design.
