FPGA

openwifi's hardware lives in the openwifi-hw repository and is built on top of the Analog Devices HDL reference designs: openwifi adds its own IP cores and modifications to ADI's board projects. For anything that isn't openwifi-specific, the ADI wiki is often the fastest source of answers.

• FPGA Development is the workflow: building, deploying, and porting the design. Start here when you want to build or change the design.

• FPGA IP Cores is the reference: the signal chain and a per-core breakdown, including how each core exposes itself to the driver through its register space. Start here when you want to understand what a core does or what a register write actually reaches.

• FPGA Simulation and Testbenches is the verification environment: how to run the receiver and transmitter testbenches, what to feed them, and which signals and dumped files to check. Start here when you want to test a change without a board.

If you are reading the register reference and want to know what is on the other end of a register write, go to FPGA IP Cores. If you have a working understanding of the cores and want to rebuild or port the design, go to FPGA Development.
