Underlying the increased importance of power distribution and c0onsumption, Cadence Design Systems, Inc. has acquired Sigrity, Inc., a signal and power integrity technology provider. The acquisition was completed on July 2, 2012 at a purchase price of approximately $80 million.

Sigrity provides a set of gigabit signal and power network analysis technologies, including a power-aware signal integrity analysis capability for system, printed circuit board (PCB), and IC package designs. 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.
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.
The integrated solution will strengthen Cadence's market presence in both PCB and packaging sectors and follows the stated philosophy of focusing on the IC as a key constituent of a PCB system.
"Increasing use of high-performance, multi-gigahertz systems underscores the need for advanced and accurate signal, power and thermal analysis solutions," said Nimish Modi, senior vice president, System and Software Group at Cadence. "Sigrity is the leading solution provider in the market, and the integrated Cadence and Sigrity products will deliver a predictable path for design and verification of high-performance PCB-based systems, speeding end product delivery."
