SAN JOSE, CA, Oct. 27, 2009 (Marketwire) --

SAN JOSE, CA -- (Marketwire) -- 10/27/09 -- Cadence Design Systems, Inc. (NASDAQ: CDNS), the leader in global electronic design innovation, announced today the latest release of its Cadence® Allegro® and OrCAD® printed circuit board (PCB) software, with new features and functionality designed to boost productivity and performance for PCB engineers. The Allegro and OrCAD PCB Design Release 16.3 brings PCB engineers significant new benefits, including the ability to miniaturize the footprint of their end product and reduce the number of physical prototype iterations, making the design cycle more predictable.

This release addresses increased functional and interconnect density through improvements for rigid-flex routing, extended high-density interconnect (HDI) rules, 3D viewing of PCBs and asymmetrical clearance for RF circuits. Extended micro via stacking rules allow users to create the most difficult HDI designs, and multi-line curved bus routing that hugs the flex outline accelerates the creation of rigid-flex designs. Additionally, an integrated 3D PCB viewer gives designers visibility into components and HDI micro via breakouts, thus eliminating unnecessary iterations with mechanical design teams. The Allegro PCB RF Option also helps engineers speed the time to create accurate RF circuits through the use of asymmetrical clearances for one or more RF elements.

"We participated in the multiphase beta program for release 16.3 and were very impressed," said Vincent Di Lello, senior PCB designer at Kaleidescape Canada, Inc. "The improvements in this new version address our miniaturization design challenges very well, and we look forward to adopting this new release into our design flow at the earliest opportunity after it is available."

The new Allegro and OrCAD release uses a multi-phase pre-release approach to help ensure that content and quality meet customers needs. More than 20 customers from North America, Europe, Asia and Japan participated in the multi-phase beta program. Customers and Cadence partners that participated in the beta program include NVIDIA, Emerson, Kaleidescape, Freedom CAD, Nordcad, FlowCAD, Graser and Tektronix.

Also featured in the 16.3 release are a number of significant productivity and usability improvements to the OrCAD family of products. OrCAD Capture CIS, for instance, now offers autowire capability to quickly add connections, as well as new 3D footprint viewing. OrCAD PCB Editor provides 3D viewing and "flip-board" design/editing and jumper support for single-sided PCB designs.
