IBM, Chartered Offer ARM Artisan Low-Power IP And High-Speed PHYS For 90-Nanometer Common Platform

Companies extend relationship to offer foundry customers sophisticated, low-power design techniques and high-speed connectivity solutions

CAMBRIDGE, UK – May 25 2005 – ARM [(LSE:ARM); (Nasdaq:ARMHY)] today announced that IBM and Chartered Semiconductor Manufacturing are offering the ARM^® Artisan^®Metro^TM low-power platform and the ARM Artisan Velocity^TM high-speed PHY Series for their jointly developed 90-nanometer (nm) common process platform. The availability of the ARM technology is an expansion of the companies’ existing agreements to enable design compatibility and manufacturing flexibility for foundry Partners; the ARM Artisan physical IP solutions move sophisticated, low-power design techniques and high-speed connectivity capabilities into the mainstream of system-on-chip (SoC) design for foundries.

“ARM’s 90nm IP development of their Artisan low-power platform and high-speed PHY products offers significant advantages for our mutual customers,” said Steve Longoria, vice president, Semiconductor Technology Platform for IBM. “The addition of these critical elements to the IBM-Chartered common process platform allows us to deliver advanced, low-power design techniques to the mainstream SoC design community that is primarily focused on application areas such as low-power and high-speed connectivity.”

“The availability of the ARM IP is an integral design component within the IBM-Chartered common platform ecosystem for helping mutual customers bring 90nm-based designs to market more quickly,” said Kevin Meyer, vice president of Worldwide Marketing at Chartered.  “We continue to broaden our relationship with ARM in support of our efforts to deliver integrated, manufacturing-aware, 90nm design solutions for the SoC design community.”

Artisan Low-Power Platform

Extending ARM’s current library support for the IBM-Chartered 90nm common process platform, the ARM physical IP products include the Artisan Metro low-power standard cells, I/Os and memories that are optimized for low-power designs. All products are characterized for timing and power over an extended range of voltages, enabling designers to perform accurate pre-tapeout simulation of multi-voltage designs. The IP conforms to the Artisan design standard that supports recent releases of leading EDA tools, simplifying power-optimized design and increasing design productivity.

The suite of products enables advanced power management methodologies by providing library components such as voltage level shifters and power gating cells for use with both memories and standard cell blocks. Front-end views for these libraries are immediately available at no charge to customers of IBM and Chartered.

The physical IP products have been designed in close collaboration with industry-leading EDA partners to ensure compatibility with the companies’ tools. Delivering advanced low-power design techniques to the mainstream SoC design community is a core area of focus for ARM’s participation with Cadence Design Systems, Inc., Magma Design Systems, Inc. and Synopsys, Inc.

Artisan High-Speed PHY Series

Additionally, ARM will offer design kits for its Artisan Velocity PHY (physical layer) series that address high-speed interconnect standards with low-jitter IP solutions.  The PHYs meet the stringent requirements for high-speed serial interconnect standards such as PCI Express, Serial ATA and XAUI. The PHYs provide comprehensive support for leading EDA tools and are delivered with extensive documentation.

“Implementing our products on IBM-Chartered’s 90nm low-power process brings our users and the industry at-large a proven and unique approach to their SoC design needs,” said Neal Carney, vice president of Marketing, Physical IP, ARM. “It is a positive development for SoC designers to have this type of compatibility and flexibility among foundries, third-party IP provider and EDA companies, especially at the leading-edge of process technology.”
