ArriaGX PCIe Kit, how to start custom implementation

I have an ArriaGX Development Kit and I am struggling to use the PCIe interface into my application. I would need some advices.

I really would like to start from the easiest application to then add my specific logics. I was trying to understand, for example, the application PCIe_HighPerformanceDesign to then adapt it to my application but, at this stage, it is too complicated for what I want to do.

By now I would like only to access some registers into the FPGA by means of the PCIe core.

i can use the Wizard to create an Avalon-ST PCIe core for example, but then I don't know what I should do in the following... Would anyone have an advice on how to start?

    Thanks for your answer rodwill,

    Well, if I use the MegaWizard Plug-in Manager at the end I have both interfaces Avalon-ST and Avalon-MM. Then, if I am not wrong, I can construct my application over the Avalon-MM interface.

    For the Avalon-MM I see many input/output ports and I should create a logic to control these ports. Let's say I want to make a test to read a register from the PC. What are the ports that are important to me? I could use only the CRA Slave Port by now?

    :confused:

    Some one could clarify those points to me. Thanks!
