The Cadence® Sigrity™ PowerSI® environment provides fast and accurate full-wave electrical analysis of leading-edge IC packages and PCBs to overcome increasingly challenging design issues such as simultaneous switching noise (SSN), signal coupling, problematic decoupling capacitor implementations, and design regions that are under or over target voltage levels. The Sigrity PowerSI approach can be used before layout to develop power integrity (PI) and signal integrity (SI) guidelines as well as post-layout to verify performance and improve designs without a physical prototype. PowerSI capabilities can be readily used in popular PCB, IC package, and system-in-package (SiP) design flows.
