X, Y. Process will terminate. To resolve this error, please consult the

What does this mean?

Solution

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.
