1.15.3. Ping Pong PHY Operation

To use the Ping Pong PHY, proceed as described below.
  1. Configure a single memory interface according to your requirements.
  2. Select the Enable Ping Pong PHY option in the Advanced PHY Options section of the PHY Settings tab in the DDR3 parameter editor.

The Quartus Prime software then replicates the interface, resulting in two memory controllers and a shared PHY, with the gasket block inserted between the controllers and PHY. The system makes the necessary modifications to top-level component connections, as well as the PHY read and write datapaths, and the AFI mux, without further input from you.
