The Video Frame Buffer Read and Video Frame Buffer Write cores are validated at AMD to represent many different parameterizations. A test design was developed for the core that incorporated a processor, AXI4-Lite interconnect, and various other peripherals. The processor was responsible for:
- Programing the video clock to match the tested video resolution
- Configuring the video IP cores with different resolutions
- Launching the test
- Reporting the Pass/Fail status of the test and any errors that were found
