PCIe packet in cyclone VI GX

thank you very much Matthias for this information.

I am a beginner in PCIe.

I read the PCIe spec, I also read Altera 's documents (IP for PCI Express Compiler user guide, PCI Epress High Performance Reference Desing ...)

but they just explained the PCIe Hard IP configuration, with the generation of chainning DMA example.

so my question is about the PCIe hard IP interfacing.?if i should use the chainnig DMA example, how can i do that and what steps should I take to send a transaction from an endpoint to another?

because i just configured the PCIe hard IP in Megawizzrd plyg-in and i'm stuck.

if you can send me an example design which shows sending transaction from an endpoint to an other.?

thanks
