Implementing custom DDR controller in Cyclone SOC

Hi, I understand that there are external DDR memory devices attached to HPS and FPGA section in Cyclone SOC. Is it possible to have my own DDR controller in the FPGA section and use the ...

Hi,

I don't have any direct experience with this but based on this document www.altera.com/literature/wp/wp-01188-hard-memory-controller-cv.pdf it seems like it is possible. Specifically it states that the memory controller can be bypassed (Bottom of page 2). I would probably confirm this with Altera though.

The Altera Cyclone V SOC Development Kit would be a good board to try this on since it has dedicated DDR3 for the FPGA as well as a hard memory controller and phy for the FPGA.
