Advanced High-Speed Signal Integrity Analysis in MATLAB | Design and Analyze High-Speed SerDes Links in MATLAB, Part 3

The final part of this series focuses on advanced techniques for channel modeling and simulation in high-speed digital systems. Engineers working on SerDes interfaces can use this workflow to gain deeper insight into signal degradation, jitter, and equalization performance.

Start by importing S-parameter data from Touchstone files and defining transmission line characteristics. Adjust trace properties, merge multiple S-parameter files, and perform parametric sweeps to explore how channel variations affect signal integrity. These capabilities allow for rapid exploration of design tradeoffs and early identification of performance bottlenecks.

Visualize simulation results using a wide range of plots, including insertion loss, return loss, time-domain reflectometry (TDR), persistent eye diagrams, and bit error rate (BER) curves. These visualizations help quantify the impact of channel impairments and guide design decisions.

Debug IBIS-AMI models by adjusting equalizer tap weights and observing their real-time effect on eye diagrams. This hands-on approach enables engineers to fine-tune equalization strategies and validate model behavior against expected performance.

You’ll learn how MATLAB^® provides a unified environment for signal integrity analysis, model debugging, and system-level simulation. By integrating SerDes modeling with channel analysis, engineers can streamline their workflow and improve the signal integrity of high-speed digital links.
