Using Intel PCIe User APP example

Hi there,

I have created a PCIe interface on a Cyclone V device - simulation only at this point in time as I don't have the appropriate development kit!

I have simulated the system using the generated BFM example and User APP logic.

Now I wish to drill down into the example User APP logic as a basis for doing my custom stuff.

If I am right, in the example file (altpcierd_example_app_chaining.v) there is a module called "altpcierd_tx_req_reg" which is set up to just assign the inputs to the outputs. If I edit this behaviour (i.e. insert a register stage) then I break the chaining_dma example from the BFM host. Is this actually an appropriate place to start experimentation and extracting the raw data that has been transported to the FPGA over the PCIe interface? Or is this too example dependant?

Any help in further understanding this would be greatly appreciated!

Many thanks

Alex

    Hi,

    Appreciate it if you can share the "example User APP logic" so that I understand more about the problem that you facing?
