ANSYS SIwave software analyzes the printed circuit boards (PCBs) and IC packages prevalent in modern electronic products. This includes packages merged onto boards for complete channel analysis. The tool allows you to perform complete signal- and power- integrity analyses from DC to beyond 10 Gb/s. SIwave extracts frequency-dependent circuit models of signal nets and power distribution networks directly from electrical CAD layout (ECAD) databases. These analyses aid in the identification of signal- and power-integrity problems and are critical to designers seeking first-pass system success. Entire design paths from package to board to package can be analyzed using a full-wave electromagnetic simulator that realizes coupling effects between packages and boards that are often ignored. With the IC die network modeler, first-order silicon effects can be included in the analyses for a complete channel description. The inclusion of Apache RedHawk™ die models enables analysis of dynamic switching effects.

SIwave excited with a 1.2V voltage source, predicts the near-field magnetic field magnitude at 778 MHz. Red indicates hot spots in A/m.
SIwave employs specialized full-wave finite element engines to compute resonances, reflections, inter-trace coupling, simultaneous switching noise, power/ground bounce, DC voltage/current distributions as well as near- and far-field radiation patterns, on high-speed PCBs and complex IC packages. SIwave can extract complete designs (which include multiple, arbitrarily shaped power/ground layers, vias, signal traces and circuit elements) with unprecedented accuracy and speed – all without potentially laborious layout partitioning by the user.
