12.1 PlanAhead - Export IP does not write out RPM constraints.


I am trying to export an IP by choosing to write out the RPM constraints, but the .ucf that gets written out is empty.

How can I write out the RPM constraints?


This is a known issue in the PlanAhead tool.To work aroundthe issue, you can choose to write out Physical constraints.

This has been fixed in PlanAhead tool for the ISE Design Suite 13.1 release.
