High-Speed Digital Interface Characterization Requires New Test Approach

The increasing speeds of digital interfaces to meet the ever-growing data demands of modern society places stress on design engineers. A new test methodology for measuring intra-pair skew is necessary to verify high-speed interfaces such as PCI Express. The BERT-based setup uses a new method with dual transmitters to control the phase of signals within a differential pair, enabling granular measurement of intra-pair skew. This capability is crucial for understanding and mitigating the impact of skew on BER margins at high data rates such as 64 GT/s.

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.
