Ravindra Rudraraju leads the Signal & Power Integrity team as a part of Mixed Signal IP Solutions group at Intel. Ravi did his Master’s in Electrical Engineering from University of Missouri-Rolla. He joined Intel in 2004 and worked in multiple fields ranging Electromagnetics, Signal Integrity, Power Integrity, Electrical Validation. He represented Intel at MIPI alliance for PHY spec definition. Contributed to MIPI PHY specs, other publications and patents in this field.
In the future, the complexity of circuit implementation will increase dramatically and modeling of high-speed SerDes systems will continue to be a huge challenge. Modeling equalization circuit characteristics has become extremely important to ensure the success of the final platform implementation and provide a strong signal integrity design guide. This paper reviews the common challenges of converting an existing detailed architectural model to an IBIS-AMI model and some of the ways to address these challenges. It also includes an illustration of the workflow to model Intel’s 56G PAM4 SerDes.
