IBERT core generation fails at the Map stage. When I check the ".mrp" report in the implementation directory, the following message appears:
"ERROR:Pack:2811 - Directed packing was unable to obey the user design constraints (LOC=***) which requires the combination of the symbols listed below to be packed into a single IPAD component."
How do I work around this issue?
This issue occurs if you use a clock location for an MGT reference clock. Check that you have selected a valid pin location for your input clock. Regenerate with a valid clock location.
