'Extreme integration in wireless handheld devices, for example, creates new challenges for RF performance, system signal integrity, system-level EMI, low power and communications reliability. Zoltan Cendes, chairman and chief technology officer of Ansoft. 'SIwave is a key technology for enabling the new era of mixed-signal electronics design driven by form-factor, functionality and integration,' said Dr. 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. 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. Engineers can view voltage and current distributions in all relevant geometry including vias and bond wires. 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. PITTSBURGH-(BUSINESS WIRE)-July 10, 2007-Ansoft Corporation (NASDAQ:ANST) released SIwave(TM) 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.
