Ansoft Corporation has announced the immediate availability of SIwave™ v2, a full-wave electro-magnetic field simulator. It 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. The package generates 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), and resonant mode analysis; SPICE Export; meshing; automated geometry cleanup; undo and redo; interpolating fast frequency sweep; decoupling capacitor model library with over 1,200 components and interfaces to several other products.
