Help to make and simulate a PCIe comunication

Hi.

I'm trying to simulate a PCIe comunication.

I must send a "data" to my interface PCIe and the FPGA must to take it.

Next I must know what "data" the FPGA has recived and depending of the "data" the FPGA must turn on Leds.

For example:

If I send to my inteface PCIe a word "A", my FPGA must turn on one led.

If I send to my inteface PCIe a word "B", my FPGA must turn on two leds, and so on.

Now I've made a componen in QSYS, it's builds with next devices:

- 1 Avalon-MM Cyclone V Hard IP for PCIe

- 1 Clock

- 1 PIO (Parallel I/O)

Do I need other divices from IP library?? :confused::confused:
