Ansys SIwave: Signal Integrity, Power Integrity & EMI Analysis for PCB Design

A specialised tool for power integrity, signal integrity and EMI analysis of IC packages and PCBs.

Dedicated PCB & Package Electromagnetics Simulation Software

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.

  • Full-Wave SI/PI Extraction
  • Impedance / Crosstalk/ EMI Scanning
  • Electro-Thermal Design

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.



PCB Board Modeling and Simulation

Printed circuit boards (PCBs), ICs and IC packages are used in almost all electronic products across all industries: automotive, A&D, consumer electronics, healthcare and energy. With electronics getting smaller, engineers need to design boards that are smaller than ever and incorporate all the required features. Accurate modeling and simulation of these components are key to reliable end products.

  • Shock and Vibration Analysis
  • Reliability Prediction

Electromagnetic Interference and Compatibility (EMI/EMC)

Electronic systems are often safety or mission critical. They form the backbone of global technology disruptions, from 5G-connected devices to autonomous vehicles and the Internet of Things. As performance requirements increase and electronics proliferate, the risk of interference leading to degraded performance, unintended consequences—or even failure—rises dramatically. With simulation, EMI/EMC issues can be resolved in advance, with reduced physical testing to deliver high-performance, safe and compliant designs. 

Optimise and Predict Electronics Reliability

Best practices for ensuring and predicting electronics reliability require comprehensive multi-physics simulations. Ansys ensures reliability success by developing solutions and workflows that overcome today’s biggest simulation and design challenges.
