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 ...

Is that the development board you have? There are a few of them and that particular one is the Arrow dev kit. Judging by the block diagram it has a similar memory setup as the Altera dev kit that I'm more familiar with.

The SDRAM interface connected to the FPGA side of the device should support connecting a custom SDRAM controller to the PHY but I'm not sure if that's what you are looking for. Also I don't think you can use ALTMEMPHY with Cyclone V devices, I think you can only use UniPHY on newer FPGAs/SoCs.
