1.12. Using a Custom Controller
If you want to use your own custom controller with the UniPHY PHY, check the Generate PHY only box on the PHY Settings tab of the parameter editor and generate the IP. The resulting top-level IP consists of only the sequencer, UniPHY datapath, and PLL/DLL — the shaded area in the figure below.
The AFI interface is exposed at the top-level of the generated IP core; you can connect the AFI interface to your custom controller.
When you enable Generate PHY only, the generated example designs include the memory controller appropriately instantiated to mediate read/write commands from the traffic generator to the PHY-only IP.
For information on the AFI protocol, refer to the AFI 3.0 Specification, in this chapter. For information on the example designs, refer to Chapter 9, Example Designs, in this volume.
