Synopsys’ Star-RCXT Powers 90 Nanometer Cell-Based LSI Design for NEC

9/10/2003 - Synopsys, Inc. (Nasdaq: SNPS), the world leader in semiconductor design software, announced that NEC Electronics Corporation has adopted Star-RCXT(TM) for its 90 nanometer CB-90 design flow. Star-RCXT’s industry-first support for advanced copper features enables NEC Electronics to meet timing and signal integrity sign-off accuracy goals for designs using their 90-nanometer process. Star-RCXT is a key component of Synopsys’ GalaxyTM Design Platform and provides implementation and sign-off extraction with support for a broad array of process technologies and design styles.

NEC Electronics’ CB-90 ASIC design platform utilizes its most advanced system LSI process technology, supporting clock speeds up to one gigahertz (1 GHz) and featuring up to 100 million usable gates. CB-90 provides leading-edge process technology for next-generation ASIC devices for low-power, high-performance applications such as broadband communications equipment, high-end computing and storage systems, and mobile computing devices.

“For designs utilizing our CB-90 process, we required comprehensive support for advanced fine copper process characteristics during extraction,” stated Toshiyuki Saito, department manager, High-end Design Technology Development Group of the Technology Foundation Development Division, NEC Electronics Corporation. “We selected Synopsys as co-development partner of our standard sign-off extraction for 90 nanometer cell-based designs because Synopsys’ Star-RCXT delivers the high performance and capacity for our requirements. Star-RCXT also achieves high accuracy with our RC modeling methodology.”

NEC Electronics Corporation and Synopsys collaborated to improve Star-RCXT’s advanced interconnection modeling technology for CB-90’s fine copper process features, which includes spacing, width and metal density-dependent wire resistance and capacitance calculation. Accurate modeling of width and thickness variations within 90 nanometer designs that use copper-based wiring is essential for high accuracy timing and signal integrity sign-off analysis.

“We partner with leading semiconductor companies to ensure that Star-RCXT continues to address the challenges of advanced process technologies,” said Antun Domic, senior vice president and general manager, Implementation Group at Synopsys. “NEC Electronics’ adoption of Star-RCXT for its advanced 90 nanometer process further demonstrates that our focus on industry-leading research and development meets the most critical needs of our customers.”

Star-RCXT provides the extraction backbone used for implementation and sign-off within Synopsys’ Galaxy Design Platform for full-chip cell-based and transistor-level applications. According to Dataquest, Star-RCXT has been ranked as the number one parasitic extraction tool for the past five years.
