CoWare Renews Contract to Supply ARM IP Models to ESL Designers; Agreement Covers SystemC Models for Current and Future ARM Processors

MUNICH, Germany--March 6, 2006--CoWare(R) Inc., the leading supplier of electronic system-level (ESL) design software and services, announced today that it renewed its Model Distribution agreement with ARM ((LSE: ARM); (Nasdaq: ARMHY)) to supply SystemC models for ARM(R) Intellectual Property (IP) to users of its ESL design tools. The agreement covers a broad range of ARM processor models from the ARM RealView Model Library including the ARM 7(TM), the ARM 9(TM), the ARM10(TM), the ARM11(TM) and the Cortex(TM) processor families. These can be integrated with the AMBA(R) 2 AHB(TM) and AMBA 3 AXI(TM) interconnect and PrimeCell(R) peripheral models. This secures the ongoing supply of SystemC models of ARM IP currently available in the CoWare Model Library for mutual customers of ARM and CoWare, as well as the timely provision of SystemC models for new IP in ARM's roadmap.

"We are currently designing SoCs with ARM processors and AMBA interconnect, using transaction-level SystemC models in CoWare's ESL tools," said Mr. Akira Usui, design manager, YAMAHA Corporation. "We are very pleased that ARM and CoWare have entered into this agreement so that we will be able to continue to receive models and support for ARM IP from CoWare."

"As system-on-chip complexity increases, ESL design is becoming more popular, and that requires IP models for the ESL design flow to be readily available," stated Tim Holden, director of EDA Services, ARM. "In addition to developing our own RealView(R) ESL tools, we have been working successfully with CoWare for many years. ARM is fully committed to ESL design and will continue to supply CoWare with ARM IP models from the ARM RealView Model Library in a timely manner, for the benefit of mutual customers."

"ARM processors continue to power the vast majority of mobile devices in high-volume consumer markets, where the need to work at the ES level to optimize designs for performance, low power, and cost is most acute," said AK Kalekos, vice president marketing and business development, CoWare. "Through our continuing strong relationship with ARM, we are able to provide models that significantly lower the barriers to adoption, to more quickly experience the benefits of ESL design."

Availability

ARM IP models for CoWare tools are exclusively available from and supported by CoWare. About 30 different SystemC models of ARM processors, interconnect, and peripheral IP are available today in the CoWare Model Library. New models are frequently added as they become available.
