I'm trying to implement a Quarter-rate Generic SDR PHY module so that I can run a CPU at 40MHz with the SDRAM at 160MHz. It looked straight-forward at first but I don't really know what I'm doing and haven't had much success. If anyone could provide any tips or examples of how to implement this it would be appreciated.

I mashed together the code from HalfRateGENSDRPHY and S6QuarterRateDDRPHY, and it's not working, the memtest fails, but maybe somebody can tell me where I'm going wrong?

Your best bet is to make a PR of your changes to this repo that makes it easier to look at the diff and will (hopefully) be merged.
