SAN JOSE – Cadence Design Systems today said it has acquired Sigrity for approximately $80 million.

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 combination of Sigrity analysis technologies with Cadence Allegro and OrCAD design tools will provide a front-to-back integrated flow to enable delivery of devices employing gigabit interface protocols such as DDR and PCI Express, the firm says.

The transaction is expected to be slightly dilutive to fiscal 2012 earnings, and slightly accretive for 2013.  The amortization of Sigrity’s deferred revenue will be substantially complete by the end of fiscal 2013, Cadence says.

The transaction is not expected to impact Cadence’s previously disclosed profitability goals for fiscal 2013.
