Cdma-Wcdma> Synopsys eyes Cossap kits for 3G phones By Loring Wirbel EE Times (02/17/99, 10:17 a.m. EDT) NICE, France — Synopsys Inc. is fielding a special suite of Cossap tools for developers of third-generation (3G) digital cellular phones, particularly those based on the wideband code-division multiple-access (W-CDMA) proposals from NTT DoCoMo, the mobile communications arm of Japan's telephone system. At this week's GSM World Congress, Synopsys' Professional Services group will not only offer a dedicated W-CDMA suite for Cossap but also promote a tool suite for MPEG-2, believing that many developers in wideband wireless markets will be adding video compression. Johannes Stahl, director of design methodologies in Professional Services, said preparing for a range of bandwidths and capabilities implies some design reuse, "but most designers still think of reuse at the RTL level, while we speak of it at the systems level." Second-tier GSM handset developers, with little expertise in baseband DSP and IF/RF analog stages, are coming into the 3G world with needs for design services that span concept to implementation. Assault on wireless The Synopsys move is part of a general assault on wireless fronts, as evidenced by Cadence Design Systems Inc.'s initial appearance at the Wireless '99 show early this month (see Feb. 8, page 4). But Synopsys' Cossap tools provide enough depth in the DSP space to allow for algorithmic verification of link-level CDMA transmission. System models include advanced CDMA functions, including channel encode/decode, rake receivers, orthogonal variable-length code generation and scrambling code generation. All models are optimized for using Monte Carlo simulation methodologies for fast link-level verification. The W-CDMA kit has been developed under the assumption that some form of wideband extension to CDMA will be the preferred 3G air interface. This has become a problem, since Qualcomm Inc. complained about the way the European Telecommunication Standards Institute has favored the NTT DoCoMo proposal and because some U.S. GSM supporters prefer a TDMA interface for 3G. The Synopsys package is flexible enough to accommodate any W-CDMA changes to chipping rate, pilot tones and other minor design changes, but a separate product for TDMA systems may be developed if the market so dictates. Single-seat license prices for the W-CDMA package start at $75,000, with special optional modules available for the kit for custom designs. The MPEG-2 design kit is priced at $20,000.
