Paris, France--Feb. 23, 1998--Cadence Design Systems, Inc. (San Jose) announced an initiative focused on the design of third-generation personal communication systems at the DATE 98 international conference. Cadence is expanding its Alta technology portfolio to include the new Enwave CDMA Toolkit and an enhanced version of the Visual Architect behavioral synthesis product. These are complemented by a suite of professional services that help designers overcome the considerable challenges of code-division multiple access (CDMA)-based product development.
In support of its initiative, Cadence has become the first electronic design automation (EDA) corporation to join the Universal Mobile Telecommunications Systems (UMTS) Forum, a consortium chartered by the European electronics community to develop newtechnologies and standards. Cadence will provide a basis for independent assessment of UMTS proposals, incorporate and drive adoption of accepted standards, and accelerate deployment of the UMTS service by offering member companies access to Cadence'scommunication systems design software and expertise.
The Enwave CDMA Toolkit greatly expedites the design of CDMA-based systems by facilitating both conceptual exploration and rapid hardware development. It addresses complexity and time-to-market challenges of system and hardware designers through earlyalgorithmic optimization and a rapid hardware design methodology. Design expertise is packaged in the form of a rich selection of graphical building blocks for designing wireless and wired communications systems. This saves system designers the many weeks ofeffort required to develop and debug from scratch complex CDMA-based functionality, such as sequence generation, modulation/demodulation, code acquisition and tracking, and others.
The CDMA Toolkit contains a library of floating-point algorithmic blocks that can be graphically configured into a system testbench. This provides an abstracted executable model of the product and its operational environment to explore the functionality and performance of a proposed system early in the design process-before detailed implementation is conducted. That same system test bench serves as a "golden reference" against which subsequent design refinements are verified. Additionally, using the toolkit's matching library of fixed-point algorithmic blocks, designers can evaluate the implications of the fixed-point datapath (signal path) on system performance. Designers can quickly perform datapath optimization to minimize silicon area and power consumption while ensuring that performance specifications are met.
Building on the Enwave Communications Toolkit announced last year, the CDMA Toolkit works with Cadence's Alta SPW, HDS, and Visual Architect tools, as well as the company's hardware design and verification products, to provide a complete concept-to-implementation design flow.
Once a system test bench is created using the CDMA Toolkit, behavioral hardware description language (B-HDL) code can be automatically generated as input for the Visual Architect behavioral synthesis tool. The Visual Architect product has been enhanced toaccommodate multirate design, a critical element of a CDMA-based design flow. The resulting register transfer level HDL description is then processed by logic synthesis tools and subsequently by integrated circuit design tools. The streamlined, integrated system and chip design methodology allows a single conceptual design to be quickly retargeted to new silicon technologies.
The perceived opportunity brought about by the third-generation wave is compelling. As a result, many companies strongly desire to enter the market, especially the consumer-oriented handset market. Cadence's professional services organization provides a wide range of relevant skills and manpower to complement customers' strengths in tackling the extreme technical complexity and market pressures of designing CDMA-based products. Expertise within Cadence's Design Factory network spans the range from algorithmic optimization to detailed integrated circuit design and encompasses all CDMA-oriented applications.
For example, Cadence recently delivered a custom verification environment (i.e., a system test bench) to a company that proposed a new wideband CDMA air interface standard. This verification environment gave the customer high confidence in the conceptual approach andserved as an executable specification with which to promote the proposal standard.
The Enwave CDMA Toolkit and enhanced Visual Architect behavioral synthesis product are available immediately for Unix-based workstations from Sun Microsystems and Hewlett-Packard. They are U.S. list priced starting at $20,000 and $70,000, respectively. The new release of the Visual Architect product will be shipped at no charge to current customers on software maintenance.
