More scope for signal-integrity analysis
Ansoft has released a new version of SIwave, its full-wave electromagnetic field simulator for analysing signal- and power-integrity effects in high-performance PCBs and IC packages.
Ansoft has released a new version of SIwave, its full-wave electromagnetic field simulator for analysing signal- and power-integrity effects in high-performance PCBs and IC packages The proprietary full-wave, finite-element technique of SIwave allows designers to characterise simultaneous switching noise (SSN), intersymbol interference, power and ground bounce, resonances, reflections and coupling between traces and power/ground planes

IC packaging partnership proves a success
IC packaging leader Advanced Semiconductor Engineering has announced its commitment to Ansoft's HFSS, Q3D Extractor and AnsoftLinks simulation products for IC packaging design and model extraction.
High-frequency simulation adds Spice to comms
Ansoft has announced version 8.0 of the Ansoft High Frequency Structure Simulator (Ansoft HFSS).
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 v2 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; and interfaces to Cadence Allegro, Cadence Advanced Package Designer (APD), Zuken CR-5000, Synopsys Encore IC Package Designer, Mentor Board Station and Mentor Expedition.
