Cray Accelerates Development of Next-Generation Supercomputer Using Cadence Virtuoso Layout Migrate and Engineering Services

   Cadence Collaborates with Cray Migrating Full-Custom 90nm Memory
      Arrays and Cell Libraries to Save 6 Months Development Time

   Cadence Design Systems, Inc. (NYSE:CDN) (Nasdaq:CDN) and global
supercomputer leader Cray Inc. (Nasdaq:CRAY) today announced that the
companies completed a project to migrate the full-custom layouts of
the memory arrays and cell libraries for Cray's next-generation vector
processing technology to Texas Instruments' latest 90-nanometer
process technology. The migration effort was accomplished by a team of
Cray and Cadence engineers using the most advanced layout migration
technology from Cadence, the Virtuoso(R) Layout Migrate product
offering. By using the Cadence technology, the team saved significant
research and development expense and nearly six months in schedule.
   During this development, the Cray-Cadence team was tasked with
migrating the custom layouts for five memory arrays within the CPU, as
well as the layout for more than 1,000 cell library elements used to
implement other portions of the CPU. Cray engineers provided detailed
knowledge of the CPU architecture, original technology process
characteristics and previous implementations, while Cadence engineers
contributed deep expertise in device/cell layout migration in
90-nanometer geometries using automation.
   "The Cadence Virtuoso Layout Migrate technology and the expertise
of the Cadence Engineering Services team helped us tremendously in
maintaining our aggressive schedule for this important technology,"
said Dave Kiefer, vice president of engineering. "Given how hard we've
been pushing the process technology and the CAD tools on this
development, that's a real accomplishment. Leveraging Cadence's
advanced technology and expertise for device/cell layout migration
enabled us to achieve some major technology breakthroughs."
   "Cray and the advanced machines they develop are a national
treasure, and we appreciate such opportunities to utilize our
technology and our design expertise," said Tim Henricks, vice
president for North American engineering services, Cadence Design
Systems. "This project with Cray showed the value of complementing
technology with engineering services. Some advanced technologies have
very steep learning curves, making them difficult for customers to
adopt while 'flying solo' in time-critical projects. Our collaborative
engineering approach enables customers to apply and build expertise
using latest-generation design technologies on current projects
without compromising their development schedules."
