Hi ,

Sorry to keep you to wait this much long , I have done my research, kindly find the details.

When the PCIe HIP , setting is made as root port , the pin_perst configured as input , the same I have verified with Stratix 10 example design.

Kind find the attached screen shot for PCIe HIP for your reference which I took from the example design.

    Hi ,

    The pin_perst configured as input？

    ->From the screen shot, pin_perst is just an internal signal, but I need a pin name which can be found in the Intel® Stratix® 10 Device Family Pin Connection Guidelines. Do you mean when S10 is setting as root port, nPERST pin can be used and be configured as output?
