Fast and accurate signal/power integrity and design-stage EMI analysis, S-parameter model extraction, and frequency domain simulation
Tried and proven technology and supports large designs
Interfaces to Cadence and other vendor layout databases
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.
Features

Establishes power delivery network (PDN) guidelines for IC packages and boards
Evaluates electromagnetic coupling between geometries to enable better component, via, and decap placement
Extracts frequency-dependent S, Z, and Y parameters for package and board modeling for subsequent time domain SSN simulation
Anticipates energy leaks with near-field ration display
Assesses decoupling capacitor strategies and verifies placement effects Enables broadband modeling including accurate DC performance characterization (patent pending)
Integrates seamlessly with 3D solutions for IC packages and boards
Distributed computing option accelerates analysis time (additional license required)
Strong HSPICE flow support
Optimized for flows with Cadence SiP Layout, Allegro® Package Designer, and Allegro PCB Designer
Readily used in Mentor, Zuken, and Altium flows, accepting a mix of CAD databases where needed for multi-structure design support
