ANSYS SIwave: PCB Signal Integrity and Power Integrity Simulation for High-Speed Digital Designs
ANSYS SIwave is a purpose-built electromagnetic simulation tool for PCB signal integrity and power integrity analysis, enabling engineers to extract S-parameters, run IBIS-AMI eye diagram simulations, and compute PDN impedance profiles directly from the routed board layout. This article covers the complete SI/PI workflow — from ODB++ import through DC IR-drop, AC PDN impedance, and channel compliance reporting — with best practices for high-speed designs above 1 GHz.
