Vivado Constraints - "WARNING: [Vivado 12-584] No ports matched..." occurs on I/O placement constraints for IP


When changing I/O placement constraints for IP, the changes should be made inside the corresponding XDC constraint file and should use the IP top-level port names.

If the actual top-level design port names are used, warning messages like the following can occur which can result in invalid implementation results or unroutable conditions.

WARNING: [Vivado 12-584] No ports matched 'rld_dq[108]'. [<path_to_file>/rldram.xdc:36]

CRITICAL WARNING: [Common 17-55] 'set_property' expects at least one object. [<path_to_file>/rldram.xdc:36]


To remove these warning messages, edit the I/O placement constraints in the corresponding IP constraints file to use the IP top-level port names.
