Ansoft announces 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 able to model 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. 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; and interpolating fast frequency sweep.
