Cyclone V PCIe hard IP? Megafunction required??

Hi Joe -

I have not used PCIe in a Cyclone V. So I can't comment specifically on PCIe DMA solutions in Cyclone V. But Altera does have free (with a Quartus license) modular scatter-gather DMA cores (mSGDMA). As I said before, I highly encourage you to leverage any available reference designs applicable to what you're doing. And if you don't have a Cyclone V dev kit get one so you can run the reference designs.

Here's a PCIe end point design that includes the mSGDMAs and targets Cyclone V:

Hope this helps!
