How to Prevent Agilex 7 F-tile PMA Direct PHY TX Lane Skew

Hi, We are implementing a 16-lane custom 1.0125 Gbps TX with F-tile PMA Direct PHY IP. The 16 lanes should be bonded together and they need to have a skew of less than 0.05 UI. However, we simulated...

If you could share simple simulation folder with steps to run the simulation, that would be very helpful.

 

Thank you.
