Integrated with Cadence PCB and IC package design tools, the Sigrity solutions for signal integrity (SI) and power integrity (PI) provide advanced analysis both pre- and post-layout. Operating early in the design cycle allows for “what if” scenario exploration, sets more accurate design constraints, and reduces design iterations. Sigrity tools read and write directly to the Allegro PCB and IC package design database for fast and accurate integration of results. It provides a SPICE-based simulator and embedded field solvers for extraction of 2D and 3D structures. It supports transistor-level and behavioral I/O modeling, including power-aware simulation using IBIS models. Parallel bus and serial channel architecture can be explored pre-layout to compare alternatives, or post-layout for a comprehensive analysis of all associated signals.
Sigrity Aurora provides traditional signal and power integrity (SI / PI) analysis for pre-layout, in-design, and post-layout PCB designs. Integrated with Cadence OrCAD and Allegro PCB editing and routing technologies, Sigrity Aurora users can start analyzing early in the design cycle using “what if” exploration scenarios in order to set more accurate design constraints and reduce design iterations.

The Cadence Sigrity OptimizePI environment automates the selection and placement of decoupling capacitors (decaps) to assure products meet power-delivery network (PDN) performance targets at lowest possible cost. The Sigrity OptimizePI approach may be applied to PCBs and IC packages, or a combination of both. Sigrity analysis technologies are augmented with an efficient optimization engine to uniquely enable cost-based PDN design. Sigrity OptimizePI capabilities can fully explore the feasible design space and identify a range of candidate decap implementations, enabling users to pinpoint the ideal approach.

To reduce simultaneous switching noise, signal coupling, and target voltage ripple, Sigrity PowerSI provides fast, accurate, and detailed electrical analysis of full IC packages or PCBs. It 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 a prototype. With 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.
