SIwave™ Software: PCB Full-Wave Solver
•Datasheet: SIwave™ Software - PCB Full-Wave Solver
Ansoft Corporation recently released SIwave™ v3.5, a full-wave electromagnetic field simulator optimized for signal-integrity, power-integrity, and electromagnetic interference (EMI) analysis of high-speed printed circuit boards (PCBs) and complex integrated circuit (IC) packages.
The new release features a fast and efficient finite-element-based DC solver optimized for extraction of power rail geometry in complex low-voltage/high-current PCB and package designs. Engineers can view voltage and current distributions in all relevant geometry including vias and bond wires. In addition, users have access to voltage drop and current flow information through all layout elements (vias, bond wires, sources, resistors, inductors, etc.) in tabular format, allowing engineers to quickly identify design rule violations. SIwave v3.5, leveraging Ansoft's industry-leading adaptive mesh refinement technology, allows users to find layout problems quickly and warns of possible bond wire and via electromigration damage prior to the fabrication of a prototype.
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.
