Agilex 5E - PCIE PERST# pin - failing compilation

Hi eharalanova​,

I would suggestion you to,

Check the Critical Link MitySom Dev Kit board schematic for the the Pin and IO 
Make sure have the pin assign in the correct bank and correct voltage.
Ex. Altera Agilex 5 Premium Devkit  using 3.3v for PERST.

Try to refer to the Critical Link guide on PCIe example design
