Sigrity_PowerSI_3DMCadence® Sigrity™ PowerSI® 3D EM Extraction Option is three-dimensional (3D) full-wave and quasi-static electromagnetic field (EM) solver technology tailored for IC package and PCB design’s S-parameter model extraction for power-integrity (PI) and signal-integrity (SI) analysis.

The adaptive finite element mesh (FEM) refinement technology provides consistent accuracy for complicated 3D structures. For time-domain transient analysis, a robust low-frequency conditioning algorithm provides stable and accurate solutions down to 100Hz.
