CadenceSigrity System Explorer is a general-purpose topology exploration environment that can be used for what-if analysis of signals, power, or both signals and power together. The software enables signal and power integrity analysis using interconnect models that are pre-route (what-if), captured from measurement, or extracted using electromagnetic field (EM) tools such as Cadence Sigrity PowerSIor Sigrity PowerSI 3D EM Extraction tools. Topologies can be contained on a single fabric or span multiple boards and packages.
