The new Advanced Design System (ADS) 2006A makes it easy for designers to take advantage of RF architecture and synthesis capabilities to generate complex, high-frequency system and circuit designs within their current ADS design flow. "The ability to create an RF system, rearrange system blocks quickly to improve performance, and then implement some of the circuits straight from the simulator makes the communications system design process faster and more efficient than ever before," said Daren McClearnon, product marketing manager with Agilent's EEsof EDA division. "By building bridges from these RF architect tools to ADS, we've given ADS users access to new technology without disrupting their established design flow. Some key customers are already adding RF Architect for ADS to their license pools, so clearly they agree." Agilent acquired the sophisticated RF system architecture capabilities in GENESYS when it acquired Eagleware in August 2005. The company is retaining the Eagleware platform while integrating key technology into the ADS design flow to increase designers' speed and efficiency. The integrated capabilities in ADS 2006A include: WhatIF -- an intermediate frequency (IF) planning tool for RF system architects; Spectrasys -- the only continuous-spectrum RF system simulator with root-cause analysis; and Synthesis -- eight design assistants that implement manufacture-ready circuit-level designs, such as precise image-reject filters for RF boards. The ADS release also contains links to the Agilent Knowledge Center for real-time application help and problem-solving. The Agilent Knowledge Center is an online technical support forum and support data archive that is accessed by more than 10,000 registered users worldwide. Today, a designer can press a button in ADS and, within seconds, have explanations and advice from thousands of other experienced users worldwide. The ADS 2006A user documentation is similarly linked. A variety of other new technologies and enhancements are part of ADS 2006A, and additional information is available at For a short video presentation, visit Viewers can be eligible to win a pair of Sennheiser noise-cancelling headphones in a monthly drawing.
