Cadence Sigrity X
Sign off with confidence
Signoff-grade signal integrity, power integrity and multi-physics analysis for today's high-speed PCB, package and system designs.
Sigrity X helps engineering teams identify electrical, power delivery, electromagnetic, thermal and reliability issues earlier in the design process — before they become expensive prototype or compliance problems.

Why Sigrity X
Solve complex design challenges before prototype
Modern electronic designs combine high-speed interfaces, dense PCB layouts, advanced packages, complex power delivery networks and demanding thermal and electromagnetic requirements. Sigrity X provides a connected analysis environment that helps engineers validate performance, investigate problems and make informed design decisions earlier in the development cycle.
02
Analyse more than signal integrity
Evaluate signal integrity, power integrity, electromagnetic behaviour, EMI/EMC, thermal performance and ESD effects within a broader multi-physics workflow.
03
Work within the design flow
Use in-design and post-layout analysis to investigate issues without breaking the PCB design workflow.
04
Sign off with greater confidence
Use automated reporting, pass/fail results, accurate modelling and hardware-correlated analysis to support technical signoff.
The platform
A complete analysis platform for advanced PCB and package design
Sigrity X is Cadence's platform for signal integrity, power integrity and multi-physics analysis. It helps engineering teams validate high-speed interconnects, power delivery networks, electromagnetic behaviour, thermal performance and related reliability concerns throughout the design process.
Sigrity brings signoff-grade SI/PI analysis into the OrCAD and Allegro PCB design environment, so designers can move from layout to analysis without breaking flow. It supports pre-layout exploration, post-layout verification, in-design analysis and detailed 2D, 2.5D and 3D electromagnetic workflows.
For teams that prefer not to run analysis in-house, Sigrity also supports a collaborative workflow: an SI/PI specialist or bureau can perform the simulations and share results back into the design environment for direct review.
Cadence also includes selected Sigrity capabilities within the PCB suites at no extra cost — such as decoupling-related checks and other entry-level integrity features — so teams can start improving design robustness even before adopting the full Sigrity workflow.

Product portfolio
Sigrity X tools
Each tool addresses a specific part of the analysis flow. With token licensing, your team can access the tools it needs, when it needs them.

Licensing
Flexible access with Sigrity tokens
Traditional licensing requires each solver and analysis tool to be purchased separately, with many tools sitting idle when their engines aren't needed. Sigrity tokens give teams on-demand access to the full Sigrity X portfolio instead.
Each tool opens with a defined number of tokens. Tokens stay in use while the tool is open and return to the floating licence pool when it is closed — making licences efficient and easy to share across a team.
- 01
Launch a tool
Tokens are drawn from the shared pool.
- 02
Run your analysis
Tokens remain in use while the tool is open.
- 03
Close the tool
Tokens return to the pool for colleagues.
Example: add a 2-token pack to a 6-token pack and run several of these tools in parallel.
