T3G Develops TD-SCDMA Mobile Phone Chipset with Cadence Incisive

5/21/2004 - Cadence Design Systems, Inc. (NYSE: CDN) announced that T3G has selected the Cadence IncisiveTM functional verification platform to verify IC and develop a reference design for China's next-generation TD-SCDMA mobile phone. T3G chose the Incisive platform because it provides the speed and efficiency to significantly reduce overall verification time, critical for faster time-to-market. The creation of the reference design also accelerates the commercialization of the TD-SCDMA standard and greatly advances the development of China's TD-SCDMA mobile communications industry.

T3G is a joint venture company comprised of Datang Mobile Communications Equipment Co., Ltd., Royal Philips Electronics and Samsung Electronics. T3G specializes in providing handset companies with a complete solution that includes a system reference design, hardware platform, software, TD-SCDMA/GSM/GPRS dual-mode handset chipset design, and customized technical support. T3G verified its TD-SCDMA reference design using the Incisive unified simulator, a comprehensive verification environment that delivers full transaction-level support and unified test generation, as well as Incisive Conformal® ASIC, which provides equivalence checking to minimize the risk of silicon respins. The speed and comprehensiveness of the Incisive platform, coupled with Cadence's strong technical support, helped T3G significantly reduce its research and development time.

"T3G selected the Cadence Incisive functional verification platform for its TD-SCDMA/GSM/GPRS dual-mode handset chipset and reference design," said Dr. Chen-Hui Chiang, modem IC project leader of T3G Technology. "We've taken advantage of the Incisive unified simulator to confirm that the T3G design meets functional requirements, and the Incisive Conformal ASIC to speed up netlist signoff. We selected Cadence because of the Incisive platform's exceptional performance, and our choice has led to success. We are glad that Cadence, as the industry leader, supports the 3G TD-SCDMA handset chipset design."

The T3G member companies are working together to develop TD-SCDMA core chipsets and commercialized products, which are considered the cornerstones of the development of China's TD-SCDMA industry. Datang Mobile, an expert in TD-SCDMA technology, has developed a testing prototype for TD-SCDMA. Philips, one of the world's largest suppliers of handset core chips, is highly experienced in GSM, GPRS and 3G mobile technology, and possesses excellent IC design and production capacity. Samsung is one of the world leaders in end-product technology. The TD-SCDMA standard, developed by Datang and Siemens, has expedited operators' migration from existing second generation to third generation networks.

Cadence China Country Manager, Wayne Tang, said, "TD-SCDMA is the new mobile standard in China, and we understand that time-to-market is crucial to the success of new products based on that technology. By using Incisive Conformal ASIC, T3G can take advantage of equivalence checking and an implementation-specific functional property-checking, enabling designers to verify and debug designs quickly and exhaustively without using test vectors. Conformal ASIC reduces verification time by exhaustively verifying multi-million-gate designs orders of magnitude faster than gate-level simulation, leading to reduced time-to-market and minimizing respin risk."
