Due to a problem in the Intel® Quartus® Prime Pro Edition software version 18.0 and 18.0.1, you may see some sdc warning messages when compiling a design which instantiates the Intel® Stratix® 10 Hard IP for PCI Express* with the Link Inspector enabled. These warnings are related to the Intel® Stratix® 10 Hard IP for PCI Express* IP core sdc files: altpcie_ltssm_fifo.sdc and altpcie_link_inspector.sdc.
Here are some of the compilation warning messages:
