3.22. Integrating a Custom Controller with the Hard PHY

If you want to use your own custom memory controller, you must integrate the controller with the hard PHY to achieve a complete memory solution.

Observe the following general guidelines:

  • When you configure your external memory interface IP, ensure that you select Configuration > Hard PHY Only on the General tab in the parameter editor.
  • Consult the AFI 4.0 Specification, for detailed information on the AFI interface to the PHY.
