4.2. Evaluation with an Alternate MAC/PHY IP
You can use the 40GbE AFU example as a framework to evaluate MAC/PHY IP from third parties or your own IP. The design example instantiates the Intel FPGA MAC/PHY IP in the following AFU RTL source file:
Replace the alt_eth_ultra_0 instance shown in this figure with your own MAC/PHY IP instance. You must provide any necessary wrapper shim logic to integrate your IP within the AFU design example framework.
