I226 Ethernet Controller IBIS AMI Model eye plot issue

[AdarshKHegde]

Hi,

      I am currently using I225 IBIS AMI model, I included IBIS Package Model "i225_VQFN56_7x7_100mhz" into main I225 IBIS simulation model and using for SI simulation.

     We are interfacing I226 with a PCIe Switch.

     For the I225 PCIe Gen 2 Rx (ethernet ctrl receiving data over PCIe Gen 2 from PCIe Switch), I am getting good eye plot with wide margin as captured below. 

    But for the I225 PCIe Gen 2 Tx (ethernet ctrl sending data over PCIe Gen 2 to PCIe Switch), I am getting failing eye plot as below.

  How I can fix the issue for TX from ethernet controller.

Hi Sazzy,

                 We are using KTI226IT an external ethernet controller.

                 We have a controller which is a root complex, due to limitation of PCIe lanes we have used a PCIe switch to connect our end point Ethernet controller.
