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.
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 the 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. The 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.
