Sign off with confidence

Fast and accurate signal/power integrity & design-stage EMI analysis

Sigrity Power SI

Provides fast and accurate full-wave electrical analysis of IC packages and PCBs to overcome increasingly challenging and interrelated power, signal, and electromagnetic interference (EMI) issues

Sigrity Power DC

Sigrity PowerDC technology provides comprehensive DC analysis for today's low-voltage, high-current PCB and IC package designs. It is available with integrated thermal analysis to enable electrical and thermal co-simulation

Sigrity Speed 2000

 Sigrity SPEED2000 technology is the first and only commercially available tool for performing transient simulation of an entire IC package and/or board design. These simulations can incorporate IBIS models.

Sigrity System SI

Sigrity SystemSI technology addresses high-speed design challenges with comprehensive chip-to-chip signal integrity (SI) analysis solutions

Sigrity Optimize PI

Enable your design teams to balance decoupling capacitor (decap) cost and performance for PCBs and IC packages. Decap cost savings of 15% to 50% are typical

OrCAD Sigrity ERC

The Electrical Rules Check (ERC) enables PCB designers to screen a PCB design for signal quality without having to assign any simulation models or to be a signal integrity expert.

How PCB Designers Can Find and Fix Power Integrity Problems

Learn about Allegro® Sigrity™ PI Base through a demonstration. Sigrity technologists show how PCB designers are empowered to solve basic PI problems early in the design cycle working cooperatively with, but independent from, power integrity engineers. The demonstration will guide you step by step on how to place effective decoupling capacitors, perform DC analysis using the Sigrity PowerDC™ engine, and cross probe with PowerDC report files.

 
 
 

Sigrity Tech Tip: How PCB Designers Can Create Initial PDN Constraints Without Becoming a PI Expert

Sigrity technologists guide you step by step on how to set up your power delivery network (PDN) constraints by using straightforward IPC calculations, instead of waiting for power integrity (PI) experts to establish constraints. Learn about the Allegro Sigrity PI Base and the Allegro Sigrity PI Signoff and Optimization option.
