Locates areas needing layout changes to improve power integrity
Provides advanced modeling and PI simulation for PDN analysis
Simulates PDNs at package or board level
PFE aids in decoupling capacitor selection and placement
The Cadence® Allegro® Sigrity™ PI Base is an interactive design and analysis environment with Allegro DRC markers locating areas that need layout changes to improve power integrity (PI). In addition, advanced modeling and PI simulation is provided in support of Power Delivery Network (PDN) analysis of high-speed and/or high-current designs. The Allegro Sigrity PI Base simulates PDNs at the package or board level.
Users of the Allegro Sigrity PI Base technology can perform DC analysis using the Sigrity PowerDC engine without having to perform any manual data translation. Set-up is automated so that the default analysis settings are always in place for the user. The integrated solution for layout and analysis can be used throughout the design process. User-friendly guidance is offered to assist the layout team on how best to optimize the PDN.
Also included with the Allegro Sigrity PI Base is a power feasibility editor (PFE) to aid in decoupling capacitor selection and placement. The Allegro constraint manager is enabled with Power Integrity Constraint Sets (PICsets) that can be reused from design to design. When used during the component placement phase of PCB or IC package design, the PICset shows the layout designer where to place the decoupling capacitors so they will be most effective.
Allegro technology works together with Sigrity power integrity analysis technology
Integration of Allegro Sigrity PI Base and Allegro PCB Editor
Integrated with Allegro PCB and IC package design, editing, and routing technologies, the Allegro Sigrity PI Base provides advanced PI analysis both during and post-layout. As power and ground planes are designed and carved up to allow for signal routing and vias, the analysis engine can be invoked to determine if DC IR drop is still within specification.
The Allegro Sigrity PI Base reads and writes directly to the Allegro PCB and IC package design database for fast and accurate analysis and viewing of results. Layout designers can find first-order power integrity problems as they design. More advanced PI experts also can use this technology for quick results, but will likely defer to the advanced technology that is represented in Allegro Sigrity PI Signoff and Optimization Option for electrical-thermal co-simulation and decoupling capacitor optimization.
