3.7. Using a Custom Controller with the Hard PHY
Observe the following general guidelines:
- When you configure your external memory interface IP, ensure that you select Configuration > Hard PHY Only under the Interface group on the General tab in the parameter editor.
The AFI interface is exposed at the top-level of the generated IP core; you can connect the AFI interface to your custom controller. Consult the AFI section for more detailed information on the AFI interface to the PHY.
