My design fails during MAP with the following error:
"Running directed packing...

What does this mean?
This error occurs when MAP encounters invalid RLOC coordinates in an RPM Grid macro. The error is typically seen when a design from a previous architecture is retargetted to Virtex-4. The column spacing has changed in Virtex-4, so RPM Grid macros with multiple columns that were created for architectures prior to Virtex-4 will not work with Virtex-4. It will be necessary to upgrade any cores that encounter this problem when retargetting a design to Virtex-4.
