Cadence Delivers Advanced Verification Environment for Palladium Acceleration/Emulation System

New Capabilities Help Speed Time-to-Market and Improve Quality of First Software and First Silicon for Complex, Multi-Million-Gate SoCs

SAN JOSE, Calif.—(BUSINESS WIRE)—July 15, 2004— Cadence Design Systems, Inc. (NYSE: CDN) today announced the availability of an advanced verification environment for the industry-leading processor-based Incisive(TM) Palladium(R) acceleration/emulation system. The environment, integrated with the Incisive functional verification platform, includes new capabilities that provide the most comprehensive environment for verification of highly complex, multi-million-gate system-on-chip (SoC) designs.

Capabilities include enhanced transaction-based acceleration (TBA), verification intellectual property (IP) SpeedBridge(TM) solutions, further integration with embedded software debuggers, and additional support for multiple languages and standards -- all contributing to greater efficiency for meeting first software and first silicon success.

The Incisive TBA solution, based on the standard co-emulation modeling interface (SCE-MI), enhances simulation acceleration performance of the Palladium system by reducing communication between the testbench running on the workstation and the design under test in the emulation system. Productivity features include support of variable-length messages, a faster streaming mode, transaction recording capabilities and support of both timed and un-timed testbench components. This solution enables full congruency with the Incisive unified simulator to shorten bring-up time and assure reusability of the testbench and the verification IP models.

"This very comprehensive system-level design and verification methodology encompasses transaction-level abstraction, acceleration and emulation," said Christopher Tice, senior vice president and general manager, Verification Acceleration, Cadence. "For simulation acceleration users, we provide a complete flow that enables reuse of transaction-level models with high performance. For customers delivering the most complex SoC designs in the wireless, multimedia and networking segments, our new vertical solutions improve the efficiency and ease of verification that the Palladium system already delivers."

By combining bus interface solutions, software applications, hardware emulation, real world data connections, and stimulus generated by external testers into one complete environment, chips or entire systems can be comprehensively verified earlier in the development cycle -- shaving months from the verification cycle to ensure high-quality, first-pass silicon and reliable software.

The new SpeedBridge solutions available now include PCI Express with support for up to 16 lanes, Multi-Ethernet (10/100, 1GB and 10GB) with ability to connect into a "live network" or third-party testers, and Video SpeedBridge enhancements. The USB SpeedBridge solution will be available during H2 2004. Leveraging Palladium dynamic target capability, a variety of software debuggers can be connected to the emulated design, allowing hardware and software integration and debug flexibility during run time.

"The Cadence PCI Express and RGB SpeedBridges enabled us to emulate our PCI-Express graphics processor design prior to tape-out, developing our software simultaneously to the hardware, and interfacing with the PCI-Express motherboards before our chip was commercially available," said Michael Shiuan, vice president of engineering at S3 Graphics, Inc. "The Palladium-based solution is fast and easy to use, and Cadence backed this up with significant PCI Express expertise."

Delivering on the Incisive platform vision of multi-language capability, the environment adds support for Verilog 2001 as a design language and SystemC/System C Verification library (SCV) as a testbench language. This enables customers to port their code from simulation to Palladium with ease and efficiency, compressing overall verification time. SystemVerilog will also be introduced in phases starting in H2 2004.
