You may see this warning message reported when compiling the Intel® Arria® 10 PCIe* Hard IP core in Avalon-ST mode in the Intel® Quartus® Prime Pro software version 17.1 and earlier.

The warning occurs due a problem in the auto generated sdc file.


This problem is scheduled to be resolved in a future release of the Intel Quartus Prime Software.
These warnings can be safely ignored.
