Overview of ANSYS SI-WAVE

In the next couple of minutes, I'll provide an overview of ANSYS SI-WAVE, a specialized electromagnetic field solver for printed circuit boards (PCBs) and integrated circuit (IC) packages. SI-WAVE's hybrid solution offers comprehensive insights into power integrity, signal integrity, and electromagnetic interference (EMI) by integrating the effects of:

  • Power and ground paths
  • Transmission lines
  • Package and PCB resonances
  • Radiation

SI-WAVE can be seamlessly integrated into your design flow with popular electronic design automation (EDA) layout tools and file formats.

SI-WAVE DC

SI-WAVE DC focuses on the DC analysis of low voltage, high current PCBs commonly found today. It enables the assessment of critical end-to-end voltage margins to ensure reliable power delivery. Key features include:

  • Pre- and post-layout DC voltage drop analysis
  • DC current density analysis
  • DC power density analysis

These analyses help visualize current flow and voltage distribution.

SI-WAVE PI

SI-WAVE PI includes all the features of SI-WAVE DC, plus AC analysis to accurately model power delivery networks and noise propagation on PCBs. It is ideal for:

  • Analyzing power integrity distribution issues
  • Automatically optimizing decoupler capacitor selection and placement

The plane resonance solver performs eigenmode analysis to evaluate the effects of cavities within PCBs and packages.

SI-WAVE

SI-WAVE combines all the functionalities of SI-WAVE DC and SI-WAVE PI, and adds robust ANSYS NEXIM time-domain circuit simulation for end-to-end signal integrity design and compliance. It can:

  • Import electrical CAD geometry
  • Extract GHz accurate interconnect models for the IC, package, and PCB
  • Include transistor-level models of drivers and receivers
  • Run simultaneous switching output (SSO) analysis
  • Perform impedance matching and power delivery system optimization

SI-WAVE supports IBIS AMI modeling, SerDes design, statistical eye analysis, and Synopsys HSPICE simulation.

Conclusion

SI-WAVE DC, SI-WAVE PI, and SI-WAVE provide a complete set of targeted analysis capabilities that can be utilized throughout the PCB design process. Use ANSYS SI-WAVE, a design platform for signal integrity (SI), power integrity (PI), and electromagnetic interference (EMI) analysis, to identify potential pre- and post-layout integrity problems.
