::::::English Description::::::

 SIwave analyzes complex printed circuit boards (PCBs) and IC packages prevalent in modern electronic products. The tool allows engineers to extract frequency-dependent circuit models of power distribution and signal nets directly from device layout (physical CAD) databases. Such circuit models aid in the identification of signal integrity and power-distribution network problems and are critical to designers seeking first-pass system success. An integrated DC IR drop computation module allows engineers to perform pre/post layout IR-drop verification to ensure that power distribution networks have the proper bump, ball, and pin sizes, as well as proper copper weighting. SIwave also helps mitigate electromigration concerns by flagging regions of high current density.
