Design for AMI: A New Integrated Workflow for Modeling 56G PAM4 SerDes Systems

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.
