TOKYO--(BUSINESS WIRE)--June 26, 2002-- Accelerated Technology, the Embedded Systems Division of Mentor Graphics (Nasdaq: MENT - News), today announced that the Innoveda Finland team responsible for E-SIM technology will be incorporated into Mentor's Embedded Systems Division.

The E-SIM product, when integrated with the Accelerated Technology® Nucleus® MNT prototyping tool, will result in the premier embedded prototyping environment. Nucleus MNT already allows embedded developers using the Nucleus operating system to prototype their embedded devices from the application down to the hardware layer. The embedded processor is replaced with a software simulation module. E-SIM will expand the capabilities of Nucleus MNT to provide for better prototyping of I/O peripherals and the man-machine interface as well as provide built-in support for regression testing.

A demonstration of E-SIM will be provided by Accelerated Technology at the Embedded Systems Expo & Conference in Tokyo, Japan. Please visit booth #19-24 to observe this technology first hand.

E-SIM is an execution platform (host-based) for embedded software development and testing. By enabling early access to native interface models, E-SIM makes it possible to begin software development before any target hardware prototypes are available. Software developers can easily observe and visualize the application's I/O operations and can even stimulate the application and drive its functionality on the fly.

E-SIM provides high-level environment modeling and tracing capabilities (virtual I/O ports, event and real-time OS tracings, etc.) for complex embedded software and networked systems (e.g. Bluetooth, CAN, WLAN, etc.).

Another benefit of E-SIM is its powerful regression testing features. E-SIM provides record/replay features, input stimulus files and a command script language, which allow complete automatic tests to be built. This makes it easy to perform regression testing of embedded software to catch unwanted side effects of software changes during both the development and maintenance phase.

With E-SIM, an array of host-based tools can be used to develop and debug an embedded application. These include Visual C/C++ IDE and debugger, code coverage tools as well as a wide variety of complementary tools from third party vendors (e.g. modelling, designing, etc.). E-SIM is available for the following platforms: Win32, Sun Solaris, HP-UX and Linux.

"The E-SIM team of Innoveda has been working diligently for the last seven years to develop world class simulation capabilities. Developers can build an on screen mock-up of their device and interact with it through keyboard and mouse clicks in addition to scripted inputs and outputs to exercise the underlying code that supports the device. This is truly a one-of-a-kind technology that will continue to keep Accelerated Technology at the leading edge of embedded systems prototyping," said Neil Henderson, general manager of Accelerated Technology, the Embedded Systems Division of Mentor Graphics.

"We are excited about this technology alliance and know that our customers will benefit from the extensive technology that Accelerated Technology has," states Timo Ronka, founder of Innoveda Finland. "We are providing higher abstract level services that will support AT's customers to leverage the scalability, reliability and maintainability of embedded software development. We see Accelerated Technology's tools as a key part of enhancing E-SIM's opportunities in the embedded world."

Pricing and Availability

E-SIM is available now through Accelerated Technology, ESD of Mentor Graphics. Licenses for E-SIM start at U.S. $12,500.
