Problem Title:
XEPLD 6.x: Unexpected error detected, please report to Xilinx with
reference "epldinst.cc40."



Problem Description:
When fitting a 7300 design with the 6.x XACTStep tools, the
partioner/optimizer fails with:

Unexpected error detetected, please report to xilinx with reference
"epldinst.cc:40", and no other error messages.

This is a bug in the EPLD tools that will not be fixed for
6.0.0/6.0.1.  It is typically caused by an OBUF driving internal
logic.	The BUG is that the tools should itemize the DRC instead
of simply issuing this cryptic code.


Solution 1:

Search the design for such violations, and fix them in the
design entry point.
