LETTER FROM THE EDITOR Welcome to Our Programmable World alph Waldo Emerson said it best: Do not go where the path may lead. Go instead where there R is no path and leave a trail. EDITOR IN CHIEF Carlis Collins Here at Xilinx, we do not follow the trends of business and technology – we set them. [email protected] 408-879-4519 Take, for example, our new family of Spartan™-3 Platform FPGAs – the first reprogrammable MANAGING EDITOR Tom Durkin [email protected] logic devices to be manufactured with the state-of-the-art 90 nm process technology. Because 90 nm 530-271-0899 device geometries enable more transistors in a smaller area, Xilinx has reduced die size with this ASSOCIATE EDITOR Jack Shandle new generation of Platform FPGAs by as much as 80 percent – and increased density to as many COPY EDITOR Charmaine Cooper Hussain as 5 million system gates with as many as 1,200 user I/Os. Perhaps most important of all, XCELL ONLINE EDITOR Tom Pyles Spartan-3 FPGAs are priced to replace ASICs in high-volume production. Now the FPGA you [email protected] 720-652-3883 use to prototype your design can be the FPGA you use in the manufacture of your design. CONTRIBUTING EDITORS Jane Middleton Peter Bergsman We are also pleased to announce in this edition of XJ the RocketPHY family of 10 Gbps CMOS ADVERTISING SALES Dan Teie Physical Layer (PHY) transceivers. Designed on a standard 0.15 µm CMOS process, RocketPHY 1-800-493-5551 devices are the first Xilinx family of Physical Layer OC-192 SONET-compliant transceivers ART DIRECTOR Scott Blair optimized for a wide range of 10 Gbps optical interconnect applications. This technology is also used in our new Virtex-II Pro™ X FPGAs. Xcell journal Many of you may be reading Xcell Journal for the first time at Programmable World 2003. Welcome to our world.

TABLE OF CONTENTS COVER STORY 2020 New RocketPHY Transceiver 7 Family Debuts at 10 GbpsE A new family of 10 Gbps serial I/O transceivers dramatically cuts costs in light-speed applications. New Spartan-3 FPGAs Are Cost-Optimized These transceivers make it possible to create unique for Design and Production optical connectivity designs. The new Xilinx Spartan-3 FPGA family offers up to 5 million system gates with the lowest cost per gate and lowest cost per I/O compared to any other programmable logic alternative. Why use a gate array or standard cell ASIC when you can get a low-cost, high-density, and faster time-to-market solution with Spartan-3 FPGAs? 46 Xcell Online Web Xclusives NSPICE Bridges Simulation Gap Check out Xcell Online (www.xilinx.com/publications/xcellonline/) A next-generation, mixed-domain for these late-breaking Xcell Online Web Xclusives and more: SPICE tool with directly integrated S-parameter data capability provides • Xilinx 300 mm and 90 nm Process Technologies: the most accurate simulation of Why This Is Important to Designers. combined silicon and system behavior. • Is Your FPGA Design Secure?
