3.1.3. Instantiation of the version_id Component
The version ID for the a10_ref Reference Platform is A0C7C1E6 in 17.1 release.
Before communicating with any part of the FPGA system, the host first reads from this version_id register to confirm the following:
- The PCIe can access the FPGA fabric successfully
- The address map matches the map in the MMD software
Update the VERSION_ID parameter in the version_id component to a new value with every agent addition or removal from the PCIe BAR 4 bus, or whenever the address map changes.
