How to test PCIe root complex on Xilinx FPGA? I would not have imaged that it is so simple as it was. So here it goes how I did it.

Step one, get some board with GT(x) Transceivers.

I had this one with Zynq 7045 from our vapor-phase oven.

It is actually a micro-module, and it pictured in working condition, junction temperature about 51C, the PCB has still the assembly tabs intact, I did not break them away as it there was enough clearance on the baseboard.
