Cadence Creates Integrated Virtuoso Platform for Accurate Wireless Design

1/25/2005 - Cadence Design Systems, Inc. (NYSE: CDN) (NASDAQ: CDN) announced new capabilities that enable wireless chip designers and manufacturers to have better insight into the mixed-signal and radio frequency (RF) challenges that significantly impact wireless design. Built upon the leading Virtuoso® custom design platform, this Cadence wireless offering combines new Cadence RF extraction technology, two new design flows tailored for wireless chip design, engineering services, silicon-proven IP, and integration with technology from industry-leading Cadence partners Agilent, CoWare, Helic, and MathWorks. This offering provides access to a streamlined design process resulting in fewer re-spins and faster time to market.

In December 2004 International Business Strategies reported that parasitics are the leading cause of failures in wireless designs. These issues are directly addressed by the system/integrated circuit (IC) flow, and the RF IC flow featuring AssuraTM RF, new Cadence technology that delivers complete extraction for RF design.

“The Virtuoso RF IC flow is a significant step forward and provides wireless designers with a substantial time-to-market advantage. The fact that Cadence uses real-world designs to streamline RF IC design front-to-back increases confidence and ensures faster implementation and adoption of new technology,” said Dr. Werner Geppert, director, Analogue Design Methodology, Infineon Technologies. “We look forward to continued collaboration with Cadence in this area.”

Based on 802.11b wireless LAN design IP, the two new design flows included in the new Cadence wireless offering focus on front-to-back RF and analogue/mixed signal design while at the same time bridging the gap between IC implementation and the entire system design. These flows enable simultaneous verification of the RF, analogue and digital domains together and verification of the wireless IC design in the context of the system.

The flows integrate technology from Cadence partners to help streamline wireless design. Designers using Cadence Virtuoso AMS Designer can work with system design teams while leveraging the proven set of wireless standards libraries available for CoWare’s SPW product. They also can move a design from the system level to the IC level more efficiently through the integration of MathWorks’ MATLAB/Simulink with Virtuoso AMS Designer. Also included in the flows are Agilent’s proven RF design and test technologies--RFDE, Momentum and Ptolemy—and Helic’s VeloceRF, an advanced inductor design solution that minimizes errors associated with RF IC design cycles.

Wireless designers who are looking for accelerated wireless flow ramp up can also benefit from Cadence wireless engineering services capabilities. These capabilities range from automated PDK development and customized flow implementation to full chip design and supply chain management. Silicon-proven IP is also available for specific wireless applications to shorten design cycle time.

"Cadence is looking forward to working even more closely with wireless designers and business leaders as we expand our focus on this market segment," said Felicia James, vice president and general manager of the Cadence Virtuoso business unit. "By extending the capabilities of the Virtuoso platform and teaming with recognized industry leaders, we are now able to offer a well-integrated platform which in turn will help our customers prevent expensive re-spins and achieve a quicker time to market."

Cadence will provide access to the wireless design capabilities through customer workshops and downloadable flow kits. For more information, contact your local Cadence sales representative or visit the Virtuoso user community at
