SANTA CLARA, CA -- NEC Electronics today announced it has launched the NEC Gate Array Design Center Internet site, a new online collaborative design environment to ease and accelerate the gate array integrated circuit (IC) design process. This dedicated site provides NEC customers with the tools and support needed to quickly and easily take advantage of the cost and performance benefits offered by gate arrays. The easy-to-use site includes real-time pricing, turnaround time and packaging information to speed the evaluation process and also facilitates quick product development through online training, design tutorials and technical and sales support. Gate array designers will also have access to popular design tools through NEC's OpenCAD(R) design environment. Using the NEC Gate Array Design Center Internet site, NEC expects that designers can improve their productivity and speed their time to market. "NEC is committed to enabling Internet-based design, and we are proud of the extensive online support and training programs we've developed to help our gate array customers cut costs and increase productivity," said Bart Ladd, assistant general manager of NEC Electronics' LSI Strategic Business Unit. "While FPGAs and cell-based ASICs are growing in popularity, gate arrays offer many cost and performance benefits for mid-range computing, networking and consumer IC designers. According to Dataquest, gate arrays represent a $2.4 billion market opportunity through 2002, and with our new collaborative design environment, we've made it even easier for designers to choose gate arrays for their IC designs." Design Environment Features NEC's Internet-based collaborative design environment includes many user-friendly features that will aid designers in the design evaluation process, including an online calculator, automatic price estimator and detailed product information on the available gate array families -- the CMOS-9HD and the CMOS-N5 (more on NEC's gate array families below). The unique online calculator enables designers to input the amount of user-defined logic, major macros and package options to easily compare the cost of gate arrays to other IC solutions. The site also provides for online delivery of all documents and contracts to facilitate easy project set-up. Once a design is in progress, the NEC Gate Array Design Center Internet site enables designers to track their engineering samples and monitor progress throughout the manufacturing process. NEC Systems, an IT consulting and solutions provider and an affiliate of NEC Corporation, designed the site's architecture to deliver an intuitive user interface and easy access to the site's key features. Through a partnership with GDA Technologies, a supplier of electronics design services, NEC's site will provide customers with front-end support, ASIC back-end services and sign-off services. In addition, GDA will provide technical support for customers using the NEC OpenCAD design environment, which includes popular third-party EDA tools as well as NEC proprietary front- end, back-end and verification design tools. Where additional assistance is needed, GDA will provide front-end design, Design For Test (DFT) services, FPGA-to-ASIC conversion, board-level validation and system qualification services. NEC Electronics is additionally working with Future Electronics as its distributor for products developed using NEC's Gate Array Design Center Internet site. "Future and NEC Electronics have a long, successful history of working together to promote products," said Jeffrey Skill, vice president, Technical Solutions Management Group, Future Electronics. "We believe that NEC's technical expertise combined with our large number of skilled technical solutions managers is a winning combination that can provide tremendous value in gate array design, development and support." Gate Array Advantages Gate arrays consist of sea-of-gates fixed arrays that are prefabricated on wafers and offer several cost and performance benefits over programmable logic or cell-based ASICs. As with FPGAs, all the prefabricated gate arrays are the same so they can be made in large volumes to keep costs down. Unlike FPGAs, gate arrays don't have programmable interconnections to take up a lot of silicon real estate and add signal delay, reducing the speed of the IC. With gate arrays, completing the final metalization step in the fabrication process interconnects the gates. This step takes much less time, and is much less expensive, than developing a cell-based ASIC. With the short turnaround time, designers can easily spin multiple versions to perfect a design, provide inexpensive upgrades or modify functionality. "With a 22 percent market share in North America, NEC Electronics is the recognized leader in the gate array market," said Bryan Lewis, chief analyst at Gartner Group's Dataquest. As the leader in gate arrays, NEC delivers the above benefits in a variety of package types, gate counts and speeds. These choices are divided into NEC's CMOS-9HD family and CMOS-N5 family. The high-density, high-speed CMOS-9HD family offers a cost-effective alternative to both high-end FPGAs and low-end cell-based ASICs. Usable gate counts in the CMOS-9HD family range from 53K to 1.5M gates. These gate arrays utilize a 0.35 um, three- or four-layer-metal process for efficient use of silicon at 15K gates/mm2. The high-speed devices operate at clock speeds up to 100 MHz and offer low power consumption by using a 3.3-volt supply with 5-volt compatibility. The CMOS-9HD family offers macros such as RAM, ROM, peripherals and PLLs. With usable gate counts ranging from 2K to 86K gates, the NEC CMOS-N5 family offers ideal replacements for moderate-capacity FPGAs. Unlike FPGAs, these gate arrays can operate at up to 60 MHz on a single 5-volt supply for power conservation and compatibility with other low-voltage chips. Using a mature 0.5 um, 2-layer-metal process, CMOS-N5 gate arrays are much more cost effective than FPGAs or cell-based ASICs. The CMOS-N5 family offers macro choices including single- and dual-port RAMs and a programmable DMA controller to UARTs. The family includes several types of flat-pack packages with pin counts as high as 304 pins. For more information visit www.necgatearray.com
