6. Design Example: Two Separate Instances of Auto-Negotiation and Link Training and Ethernet IP Design

This design example describes necessary steps to enable two separate instances of auto-negotiation and link training (AN/LT) in your design example.

When you enable auto-negotiation and link training parameter in the IP and select the design Two separate instances of ANLT, ETH IP and generate a design example, which instantiates two separate instances of IPs, F-Tile Ethernet Intel FPGA Hard IP and the F-Tile Auto-Negotiation and Link Training for Ethernet. You must connect required signals at the top level of your testbench.

The following IP parameter settings were used to generate this design example:
