3.3. Recommended Starting Point for HPS-to-FPGA Interface Designs
Depending on your topology, you can choose one of the two hardware reference designs as a starting point for your hardware design.
GUIDELINE: Intel recommends that you start with the Golden Hardware Reference Design (GHRD) as an example of interfacing the HPS to soft IP in the FPGA.
The Golden Hardware Reference Design (GHRD) has the optimum default settings and timing that you can use as a basis of your "getting started" system.
For more information, refer to the "Golden Hardware Reference Design (GHRD)" section.
