ARM and Cadence Optimize Digital SoC Design Through Expanded Collaboration; Alliance Produces Methodology Kit to Improve Performance, Power, and Area for Synthesizable ARM Processors

SANTA CLARA, Calif. & CAMBRIDGE, United Kingdom—(BUSINESS WIRE)—Sept. 12, 2005— Cadence Design Systems, Inc. (NYSE: CDN) (Nasdaq: CDN) and ARM (LSE:ARM) (Nasdaq:ARMHY) today announced they have extended their design chain alliance to deliver further benefits to their mutual customers. This phase builds on the companies' existing collaborations on digital IC design, power management and verification to provide new solutions for application-specific needs. The result is the Cadence(R) Optimization Methodology Kit for ARM(R) Processors, which helps design teams enhance performance, power utilization, and area when hardening synthesizable ARM processors.

The goal of the Cadence Kits approach is to simplify the application of Cadence technology and so shorten time-to-productivity. Customers can then focus their precious design resources on design differentiation rather than design infrastructure. Cadence Kits address application-specific design challenges by combining a verified methodology, packaged in platform flows, with IP and consulting all demonstrated on a representative reference design.

The Cadence Optimization Methodology Kit for ARM Processors builds on the success of the silicon-proven ARM-Cadence Encounter(R) Reference Methodology. In addition to the reference methodology, the kit includes Cadence Encounter RTL Compiler synthesis, First Encounter(R) silicon virtual prototyping, front-end views for the ARM Artisan(R) SAGE-X(TM) standard cell libraries for TSMC's 0.13-micron and 90-nanometer G processes, and service and support to help designers achieve high performance, low power and small area levels, while reducing development time.

As two founding members of the Silicon Design Chain Initiative, ARM and Cadence have collaborated on solutions to reduce risks and design time for their customers. For example, the companies have already delivered:

-- Low-power design techniques demonstrated to reduce power by more than 40 percent on a 90-nanometer test design.

-- Accelerated SoC emulation by integrating the Cadence Incisive(R) functional verification platform and the ARM Integrator(TM) Logic Tile products.

-- The ARM-Cadence Reference Methodology, which enables predictable performance, power and area results.

"Today's disaggregated design chain requires a more integrated, collaborative approach to massively simplify the design process," said Jan Willis, senior vice president of Industry Alliances at Cadence. "This Methodology Kit leverages expertise from both companies to help our customers rapidly reach the target frequency, die size, and power consumption requirements for their particular markets."

"At Oki, we have seen substantial power and area savings using Encounter RTL Compiler on our designs based on our uPLAT SoC System LSI Design Platform, which features the ARM946E-S(TM) processor," said Masakazu Urahama, manager of the Silicon Platform Design Department, LSI Design Division, at Oki Electric Industry Co., Ltd. "We are excited to see Cadence and ARM working together to deliver further benefits in a streamlined flow with the Cadence Optimization Methodology Kit for ARM Processors."

"ARM and Cadence originally developed the ARM-Cadence Reference Methodology to provide excellent support for our mutual customers," said Mike Inglis, executive vice president of Marketing at ARM. "As the complexity of design tasks has increased with lower-power and higher-performance requirements, we have increased our level of integration and validation with Cadence through efforts such as the Silicon Design Chain Initiative. The new Methodology Kit builds on this collaboration by providing the technology, support and training necessary to enable our Partners to achieve their specific power, performance and area goals in hardening synthesizable ARM processors."

This deepening relationship between ARM and Cadence will result in additional projects to ensure more optimized products from both companies are aligned to meet customer market requirements. Areas of collaboration include extending the companies' continuing work in advanced processor cores, system verification, and on extending the effective current source delay model (ECSM) which Cadence pioneered. The companies will expand work done through the Silicon Design Chain Initiative to add additional low-power design capabilities, and also extend support for system languages, including the e, SystemC, and SystemVerilog languages.


The Cadence Optimization Methodology Kit for ARM Processors will be available in October 2005. More information can be found at
