PCIE hard ip issue, when i try to integrate two PCIE hard IP's ,than synthesis is being failed.( family Cyclone V , gx )

Adding one more query is it possible to assign only IO's for PCIE HARD IP and do Analysis to generate the ".pin" file for the board team.

When we try the above step we are getting the compilation error as below

Error (177035): The input pin PCI_EP0_REFCLK_P assigned to HSSI Pin_W8 has no fanout.
