3.2 SGMII Channel Simulation with Eye Diagram

  1. Place an IBIS_DI and IBIS_DO component and select the dp83tg720s.ibs files for each. Select pin 23 or 24 for the output and 31 or 32 for the input. It will not matter since the pins are designated as a differential pair.

  2. Recreate the rest of the setup as shown below, and simulate.
