Optimization of IBIS-AMI Model Parameters with Machine Learning Algorithms

This article describes the use of Cadence’s Sigrity signal and power integrity solution ML optimization algorithm to quickly and efficiently converge on the best set of parameters in a set of IBIS-AMI models. The application of Sigrity was investigated for refining IBIS- AMI parameters to find the optimal set of values to maximize a specific metric.

Generative Solutions vs. Discriminative Models

The future of signal integrity design is being reshaped by AI and machine learning. Traditional SPICE and IBIS models are giving way to generative AI, digital twins, and physics-informed models that offer real-time insights and future-proofing capabilities. Chris Cheng discusses why AI is no longer just data-driven—it’s becoming physics-aware, adaptable, and ready to co-pilot your next design.

PCB Laminate Anisotropy: The Impact on Advanced Via Modeling

Since woven glass PCB substrates are anisotropic, EDA design and modeling software hoping to advance AI and ML algorithms should have provisions to model anisotropic material, especially via transitions. In this article, Bert Simonovich discusses the importance of having an awareness of the test method used by CCL suppliers for accurate modeling and simulation. Simonovich covers how the use of out-of-plane Dkz values instead of in-plane Dkxy values for via modeling can cause misleading simulation results, which may result in reduced margins and potential compliance test failures when the design is built and tested.
