Resonant Mode Analysis of a PCB using SIwave

This workshop is intended to show how to import, simulate and analyze a 4-layer board structure using ANSYS SIwave. ANSYS SIwave is a specialized design platform for Power Integrity (PI), Signal Integrity (SI) and EMI analysis of electronic packages and PCBs. In PCBs, when traces are routed through power and ground planes, you can experience SI and PI problems. The following illustration details the board design that will be used in SIwave to investigate the following SI applications:

  • How resonant behavior effects signal transmission along a trace
  • Non-ideal plane behavior
