Sigrity Unified Analysis Workbench

Complete electrical analysis platform built to help you solve all your SI, PI,  and EMC design challenges across the board 

Solve The Next Generation of Design Challenges with Sigrity

Designs are not getting simpler and delivery schedules aren’t getting longer. If you hope to stay ahead of the competition, you must determine optimal design configurations, validate performance, and signoff on your critical interconnects well before you get to prototype . Sigrity provides the only complete analysis solution designed to solve todays multi-physics, multi-domain design challenges.


Guided, Workflow-Driven Analysis

Figuring out how to set up the simulation shouldn’t take twice as long as the analysis. Sigrity provides easy to follow workflows and wizards designed to guide you through the simulation setup and analysis process quickly and efficiently. Coupled with a comprehensive model library and management environment you have a quick repeatable path to analysis that can be leveraged throughout your organization.

Hardware-Correlated Results

Analyze and verify with confidence knowing your results will have tight correlation to real-world hardware. Your analysis is only as good as the confidence in your results. Cadence rigorously tests Sigrity against their own hardware ensuring the correlation you need to sign-off with confidence.


Analyze in Your Environment Seamlessly

Regardless of your CAD environment it is easy to bring your data into Sigrity for quick and accurate analysis. Simply drag and drop your design files on the unified canvas and start running workflows. Leverage the automated reporting engine to quickly generate and share insights from your analysis with colleagues drastically cutting down on reporting time.

Easily Communicate Your Results & Insights In Real-Time

For complex interfaces like DDR or PCI, manually reporting on all the data points needed to guarantee compliance is error-prone and can take hours to create. With Sigrity, the reports and documents needed to communicate with project stakeholders are just another output of your simulation and analysis activities. Documents are easily sharable and consumable in HTML format. Compliance reports are auto-configured based on the interface specifications, ensuring you are documenting all the key metrics needed for sign-off.
