Mentor Graphics Delivers Seamless 4.2 Co-verification Environment

WILSONVILLE, Ore.--(BUSINESS WIRE)--Nov. 12, 2001--Mentor Graphics Corporation (Nasdaq:MENT - news) today announced the availability of version 4.2 of the Seamless® Co-Verification Environment(TM).

New features in Seamless 4.2 include availability on the Linux platform, tighter integration with Denali's Memory Modeler -- Advanced Verification (MMAV) product, and a second-generation CPU model interface and enhanced hardware/software debug.

Seamless 4.2 continues to offer support for the broadest range of logic simulators and software development environments, and now has models available for over 100 processor cores. The release of version 4.2 coincides with Gartner Dataquest's report which lists Mentor Graphics as the undisputed market share leader in hardware/software co-verification in 2000.(a)

Seamless Now Available On Linux

As Pentium 4 clock speeds surpass 2-Ghz, and memory-bus bandwidth approaches 800-Mhz, the personal computer has evolved into a high-performance, low-cost simulation platform. This development, in concert with the tight coupling between Seamless and logic simulation, has created customer demand for Seamless on Linux.

"Seamless 4.2 comes in response to customer demand for Linux operating system support," said Larry Anderson, director of marketing, System-on-Chip Verification Division, Mentor Graphics. "Linux support broadens our addressable market to include design groups employing PC simulation farms for verification and regression testing of complex SoC designs."

Tighter Integration with Memory Modeler -- Advanced Verification From Denali Software, Inc.

The Seamless Co-Verification environment includes a license for Denali Software's Memory Modeler -- Advanced Verification (MMAV). Customers can now download new versions of MMAV from Denali's web site, and dynamically link it with Seamless 4.2. In addition, the new integration supports both Seamless and standard Denali models in the same simulation.

"At Denali, we pride ourselves on having the highest-quality verification IP for semiconductor memories," said Kevin Silver, VP of marketing at Denali. "Native Memory Modeler -- Advanced Verification (MMAV) support in Seamless 4.2 will benefit all of our mutual customers. Seamless 4.2 users now have instant access to over 4,000 memory components on eMemory.com, and can be assured that these models are optimized for use with the latest version of Seamless."

New Modelware CPU Interface

Recent advances in embedded core architectures, such as multiple busses, split transactions, write-back buffers, and streaming cache fills have increased the effort required to develop a Seamless Processor Support Package (PSP). In response to these advances, and to feedback from its semiconductor partners, Mentor Graphics re-architected the PSP interface, resulting in the Modelware Application Program Interface (API). By incorporating functions found common across many PSPs, Modelware simplifies development, and improves the accuracy and reliability of cycle accurate Seamless PSPs for advanced architecture embedded cores.

Seamless 4.2 Enhances Hardware/Software Debug

Detecting errors in the hardware/software interface is a key capability of Seamless, but isolating and correcting the error is equally important. Vital to this process is the correlation of hardware and software execution in the respective debuggers. To this end, Seamless 4.2 adds the ability to display software time in the logic simulator waveform display. Users can now locate precisely where in software a given hardware cycle is initiated, pinpointing accurately the source of errant behavior.

Availability and Pricing

Seamless 4.2 is available on Linux, HP, Sun and IBM UNIX-based platforms. Pricing of Seamless 4.2 starts at $40,000. For more information, or to register for free Seamless workshops and SoC verification seminars, visit our web site at www.mentor.com/seamless.

Mentor Graphics Number One in Co-Verification Market

In related news, Mentor Graphics announced that it out performs its competition in the hardware/software co-verification market with a 90 percent market share in 2000 according to the most recent Gartner Dataquest study on the Electronic Design Automation (EDA) industry, "EDA 2001: It's Good to be an EDA Vendor" (10/25/2001). The market is expected to exceed $115-million in revenues in 2005.

About Seamless

Combining the best in embedded software development tools with logic simulation, the Mentor Graphics® Seamless co-verification environment delivers high performance co-verification months before a hardware prototype can be built. The Seamless environment enables software and hardware development to be carried out in parallel removing the software from the critical path, and reducing the risk of hardware prototype iterations resulting from integration errors. User-controlled optimizations boost performance by isolating the logic simulator from software-intensive operations such as RTOS initialization, block memory transfers, and algorithmic routines. Seamless supports all popular logic simulators and software development environments, including the Model Technology® ModelSim® environment.
