Arm and Co-Design Automation Provide High-Speed Co-Verification Solution for Embedded Systems

CAMBRIDGE, UK and LOS ALTOS, CALIF - Mar. 4, 2002 -- ARM [(LSE: ARM); (Nasdaq: ARMHY)], the industry's leading provider of 16/32-bit embedded RISC processor technology, and Co-Design Automation, Inc., a provider of next-generation system simulation technology, announced today at DATE, Paris, France that they have collaborated to produce a hardware/software co-verification product for embedded system designers. Co-Design Automation has also joined ARM's electronic design automation (EDA) Partnership Program.

The two companies have worked together to integrate Co-Design Automation's SYSTEMSIM™ simulator including its CBlend™ technology with the ARM® processor models and software debug environment. The new product allows the simulator to be encapsulated within an ARM core-based embedded design, accelerating simulation performance to allow pre-prototype software verification, and enabling design debug using native hardware and software development environments.

The joint solution will help reduce time-to-market by enabling software verification to start earlier in the design process, while reducing the probability of chip iterations due to functional problems. In addition, verifying real software on the hardware design prior to prototype will increase the confidence that the system will operate as expected when manufactured.

"ARM is working with a number of Partners in the emerging hardware/software co-verification space, and our collaboration with Co-Design Automation provides system developers with a further opportunity to their reduce time-to-market," said Duncan Bryan, ARM EDA Partnership Program manager. "ARM's Cycle Callable Model (CCM) technology makes good use of the CBlend technology to enable a very efficient integration within the SYSTEMSIM environment. The CBlend and CCM combination has removed the need for a co-verification kernel, which has led to impressive simulation performance while retaining overall accuracy."

"Co-Design Automation's CBlend technology allows a C program to directly drive simulation, enabling a unique, high-performance approach to platform verification," said Simon Davidmann, Co-Design Automation's president and chief executive officer. "Our collaboration has allowed the utilization of this SUPERLOG&3153;-based technology for verifying devices containing ARM models more efficiently and effectively than previously possible, significantly improving our customers design cycle time."

Availability and Pricing
The SYSTEMSIM ARM model integration is available today running on Sun Solaris and Linux operating systems. It will be distributed by Co-Design Automation through its channels worldwide.

SYSTEMSIM is available either as a perpetual or time based license, starting at $18,400 per year for a three-year contract.

About the ARM EDA Partnership Program
The ARM EDA Partnership Program brings together ARM's expertise in reusable intellectual property (IP) generation and IP modeling, with the electronic design automation (EDA) design methodology expertise of leading EDA tool vendors to develop faster, more accurate, routes to system-on-chip (SoC) products. Members include Axis Corporation, AXYS Design, Cadence, Co-Design Automation, CoWare, IKOS, Innoveda, Mentor Graphics, Synopsys and Virtio.

The Program establishes a framework of co-operation between engineering teams. The goal is to specify a range of core models, or IP views, that are developed by ARM as an integral component of the internal IP generation flow.
