Mentor Graphics Calibre to Improve Semiconductor Manufacturer's System-on-a-Chip Designs

WILSONVILLE, Ore., May 28, 2002 - Mentor Graphics Corporation (Nasdaq: MENT) today announced Texas Instruments (TI) is adding Mentor Graphics® Calibre® physical verification tool suite for TI's application-specific integrated circuit (ASIC), logic, mixed-signal and analog semiconductor processes. TI plans to use the tool suite to support key customers and technologies beginning late 2002.

"Combining Mentor Graphics Calibre rules to TI's design tool capabilities will give our customers the ability to perform comprehensive physical verification of ASIC and mixed-signal system-on-a-chip (SoC) designs," said Bill Giolma, worldwide customer-owned tooling manager, TI. "We are excited to use Calibre to help enable widespread use of TI's silicon technology with our leading customers."

The Calibre physical verification tools provide a high degree of accuracy for analog/mixed-signal designs, and allow designers developing digital and analog circuits to rapidly verify their components and the complete integrated circuit.

"Historically, some verification tools have been optimized for digital designs while others have worked better for analog flows. Our customers' application of Calibre to designs targeting analog, logic and mixed-signal processes recognizes the flow-invariant, physical verification

capability enabled by Calibre's design style independence and advanced device recognition capabilities," said Anthony Nicoli, Calibre marketing manager, Mentor Graphics.

Calibre - The Industry Standard in Physical Verification
Calibre's physical verification tool suite, Calibre DRC™ and Calibre LVS™, ensures that integrated circuit (IC) physical designs conform to foundry manufacturing rules and match the intended functionality of the chip. Calibre features design style-independent execution to provide optimal performance on designs ranging from random access memories to SoCs using a single, qualified rule file. Calibre also provides advanced debugging capabilities, including intuitive error reporting, a graphical results viewing environment and hierarchical error isolation. The combined force of design style independence and advanced debugging extend Calibre's world-class run time performance to further reduce verification time by simplifying tool set-up and error correction.
