6.3i ChipScope Pro - When I try to probe a DDR register in ChipScope Core Inserter, I get unrouted nets


General Description: 

When I try to use the ChipScope Core Inserter to utilize FDDRCPE registers as a Trigger or Data, PAR completes but there are unrouted nets in FPGA Editor and my DDR registers are not implemented in the I/O blocks (IOBs).


The FDDRCPE primitive should be grayed out and unavailable for selection in the ChipScope Core Inserter. The IOBs do not allow ChipScope access to the output of the DDR registers, and, as a result, they cannot be probed using ChipScope.
