Ansys SIwave

Signal Integrity, Power Integrity and EMI Analysis for PCB Design

Dedicated PCB and Package Electromagnetics Simulation Software

Ansys SIwave helps you model, simulate and validate high-speed channels and complete power delivery systems typical in modern high-performance electronics. It accurately extracts multi-gigabit SERDES and memory buses, providing product sign-off compliance for various designs. SIwave’s full-wave extraction of complete power distribution networks (PDN) enables you to verify noise margins and ensure impedance profiles are met through automatic decoupling analysis in low voltage designs.

Why Use Ansys SIwave?

Successful design of next-generation electronic products requires power integrity, signal integrity and thermal integrity co-analysis. SIwave uniquely handles the complexity of interconnect design from die-to-die across ICs, packages, connectors and boards. By leveraging advanced electromagnetic, thermal and mechanical simulators dynamically linked to powerful circuit and system simulation, you can understand the performance of high-speed electronic products long before building a prototype in hardware. This approach enables electronics companies to achieve a competitive advantage with faster time to market, reduced costs and improved system performance.
