Cadence Design Systems has acquired Sigrity, a signal- and power-integrity technology vendor that provides a rich set of gigabit signal and power network-analysis technologies, including a unique power-aware signal integrity analysis capability for system, PCB, and IC package designs. The Sigrity acquisition was completed early July at a purchase price of approximately $80M. The combination of Sigrity analysis technologies with Cadence Allegro and OrCAD design tools will provide a comprehensive front-to-back integrated flow to enable system and semiconductor companies to deliver high-performance devices, employing gigabit interface protocols such as DDR and PCI Express. The integration will particularly benefit customers delivering electronic systems in high-growth markets such as mobile multimedia devices and cloud computing infrastructure. "Increasing use of high-performance, multi-gigahertz systems underscores the need for advanced and accurate signal, power and thermal analysis," says Nimish Modi, senior VP, System and Software Group at Cadence. Dr. Jiayuan Fang, president of Sigrit added. "Cadence and Sigrity have worked together for years to enable design and analysis of the industry's most advanced PCBs, Systems-in-Package, and SoCs. We look forward to joining Cadence to bring the next generation of signal- and power-aware design and verification tools to the industry." Cadence expects that the transition of Sigrity's business to Cadence's ratable business model, and the amortization of Sigrity's deferred revenue will be substantially complete by the end of fiscal 2013. The transaction is not expected to impact Cadence's previously disclosed profitability goals for fiscal 2013. Cadence will offer Sigrity technologies immediately as add-on options to Cadence Allegro and OrCAD PCB and IC Packaging tools. The company will also continue to support Sigrity technologies used with third-party design software.
