Cadence Design Systems Sigrity 2019
What’s New in Sigrity 2019
Sigrity 2019 Release Accelerates PCB Design Cycles by Integrating 3D Design and 3D Analysis
Interconnect Modeling Technology
Upgraded interconnect modeling technology addresses latest trends on PCB and IC package design.With signal speeds climbing to 32Gbps and faster, the need to strategically model PCBs and connectors as one structure is now required. The new Cadence® Sigrity™ 3D Workbench, included with the Clarity 3D Solver, allows users to import mechanical structures, such as cables and connectors, and merge them with the PCB. This way critical 3D structures that cross from the board to the connector can be modeled and optimized as one structure. Updates to the PCB can be automatically back-annotated to the PCB layout tool.
The 3D Workbench offers:
- SI and PI applications
- A familiar 3D look and feel
- Ability to import mechanical structures
- Ability to import electrical databases and merge with mechanical structures
- 3D solid modeling (parametric and full featured)
- Simulation of:
- Twisted pair wiring (cables)
- Backplane plus connectors
- Connector modeling (HDMI, SATA, etc.)
- SMA connector on a PCB
Industry-first full Rigid-Flex PCB extraction from a single layout database provides accurate interconnect modeling of both rigid and meshed-ground flex cable zones. The zone information is automatically imported from version 17.2 of Cadence Allegro® technology.
- Sigrity PowerSI technology
Faster IC Package Modeling
IC package modeling of designs with thousands of bumps/balls is now 3X faster and memory consumption has been reduced by 75 percent.
- Sigrity XtractIM™ technology
Power Integrity Updates
Upgraded power integrity (PI) technology addresses new checking requirements and new usability requirements for PCB front-to-back design flows. Many enhancements have been added, including hierarchical views, quick search, and filtering, comparison tree report, and tool tips.
- Allegro PowerTree™ technology
The DC analysis technology has been upgraded to support integration with Allegro technology, HTML block-diagram enhancements, and automated add-nodes-on-pads enhancements.
- Sigrity PowerDC™ technology
The AC analysis technology has added some additional checks that now look at the weighted AC current and checks for equal voltage. New batch-mode “projects” allow these two new workflows as well as others to be setup as a set of batch checks.
- Sigrity OptimizePI™ technology
Signal Integrity Updates
Upgraded signal integrity (SI) technology accelerates the time it takes to verify memory interfaces, serial links, and the plethora of other signals on a PCB that can cause a design to fail in the lab. The technology now features workflows and visions that can be used to quickly perform electrical rule checks that find impedance variations and excessive coupling. These checks require no models and can be run by both expert and non-experts in signal integrity.
