Pittsburgh - August 17, 2004 - Ansoft Corporation (NASDAQ: ANST) today announced the immediate availability of SIwave™ v2. SIwave, a full-wave electromagnetic field simulator, analyzes signal- and power-integrity effects in high-performance printed circuit boards (PCBs) and integrated circuit (IC) packages.
SIwave's proprietary full-wave, finite-element technique allows designers to characterize simultaneous switching noise (SSN), inter-symbol interference, power and ground bounce, resonances, reflections and coupling between traces and power/ground planes. Engineers are now able to model entire PCBs and package structures using an analysis engine to generate both frequency- and time-domain results.
SIwave is fully integrated to layout tools such as Cadence Allegro and APD and Synopsys Encore. This integration adds significant value to existing EDA tools by enabling the accurate simulation and design of complex PCBs and IC packages consisting of multiple, arbitrarily shaped power and ground layers and any number of vias and signal traces.
Specific features and enhancements to SIwave include:
Power Plane Impedance
Signal Net Analysis (including coupled transmission lines)
Resonant Mode Analysis
SPICE Export
Robust meshing
Automated Geometry Cleanup
Unlimited undo and redo
Interpolating fast frequency sweep
Decoupling capacitor model library with over 1200 components
Frequency-dependent model for dielectric materials
Interfaces to:
Cadence Allegro®
Cadence Advanced Package Designer (APD)
Zuken CR-5000
Synopsys Encore IC Package Designer
Mentor Board Station®
Mentor Expedition
