    Hi ,


    Can I know which FPGA device that you are referring at ?

    also can I know which document the picture that you sent is coming from ? or from which device/IP user guide ?

    Appreciate if you can clarified to ensure that we are looking at the same picture.


    Looking forward to hear back from you.


    Regards,

        Hi,

        I am working in a startup frontend design based company. We are working on building PCIE IP from scratch.

        The snap I shared is from PCIE spec.

        Regards,
