14.2. Replacing the ALTMEMPHY Datapath with UniPHY Datapath

To replace the ALTMEMPHY datapath with the UniPHY datapath, follow these steps:
  1. In the Quartus Prime software, open the Assignment Editor, on the Assignments menu click Assignment Editor.
  2. Manually delete all of the assignments related to the external memory interface pins, except for the location assignments if you are preserving the pinout. By default, these pin names start with the mem prefix, though in your design they may have a different name.
  3. Remove the old ALTMEMPHY .qip file from the project, as follows:
    1. On the Assignments menu click Settings.
    2. Specify the old .qip, and click Remove.

Your design now uses the UniPHY datapath.
