Honored ContributorDoes your controller use the training features of the DFI interface? If so you cant use it with AFI as AltMemPHY's calibration is enclosed within the PHY. Other than that the signals pretty much line up one to one. I think there is one extra signal left in AFI but that can easily be generated in logic.
Why do you want to use Denali controller? Could you just use Altera's controller?
