Walter Katz, Ph.D., IBIS-AMI Specialist for the MathWorks. Formally Chief Scientist at SiSoft which was acquired by MathWorks in 2016. At SiSoft he was one of the developers of the QSI and QCD signal integrity and channel analysis products. Walter was one of the original developers of the IBIS-AMI standard. At MathWorks he is developing advanced SerDes modeling software and is currently working on optimization and training methods for the latest generation of IBIS-AMI models. He received his Ph.D. from the University of Rochester and a BS and MS degree from the Polytechnic Institute of Brooklyn (NYU Tandon School of Engineering),
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.
