Sigrity PowerSI

To help you tackle increasingly challenging issues related to simultaneous switching noise, signal coupling, and target voltage levels, Cadence^® Sigrity^™ PowerSI^® technology provides fast, accurate, and detailed electrical analysis of full IC packages or PCBs. It is cloud ready and can be used pre-layout to develop power- and signal-integrity guidelines, as well as post-layout to verify performance and improve a design without needing a prototype.

Using Sigrity PowerSI electromagnetic (EM) field solver technology, you can readily perform a broad range of studies to identify trace and via coupling issues, power/ground fluctuations caused by simultaneously switching outputs, and design regions that are under or over voltage targets. PowerSI technology also lets you perform extraction of frequency-dependent network parameter models and lets you visualize complex spatial relationships.
