Verifying the modulation profile of SSC has historically been challenging because it involves a frequency shift as a function of time. Mike Hertz explains that by tracking the frequency measurement parameter, an oscilloscope can display the SSC modulation profile as a function of frequency versus time. Read on to see how it’s done.

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.
