General Description: Virtex design implemented in M1.5i results
in the following error:
FATAL_ERROR:xvkma:xvkmap.c:586:1.112. Cannot find IOB attached


This particular case was due to a illegal clock circuit configuration. The 2.1i version
of map fails with a user error on this design:

ERROR:xvkpu - The symbol $I598 failed to join a global clock I/O component
as required. Clock I/O component can accept input pads only. Problem encountered
during the packing phase.
