SIwave Components

SIwave is a tool used by signal and power integrity engineers to study complex electromagnetic phenomena on printed circuit boards (PCBs) and IC packages. It can identify signal delay and excessive cross-talk between interconnects, deficiencies in the power distribution network, and regions in the layout that may cause EMC/EMI problems.

SIwave Full-Wave SPICE models are computed from broadband S-parameter data representing PCB geometry. They are compact macro-models used in circuit tools for time-domain simulations. They optionally incorporate corrections for passivity and causality violations that arise due to issues such as incorrect upstream material parameters.

Exporting an SIwave subcircuit lets you perform an analysis of the structure in Twin Builder. See the SIwave documentation for detailed information.
