NEC Electronics America, Green Hills Software and The MathWorks Develop Integrated Model-Based Software Development Solution

Integrated Solution Enables Simultaneous Simulation and Code Debugging for NEC Electronics' V850-Based Applications

electronicaUSA/Embedded Systems Conference, SAN FRANCISCO, March 30, 2004 – NEC Electronics America, Inc, today announced an agreement with Green Hills Software, Inc. and The MathWorks, Inc. to develop a complete system modeling software development solution for embedded industrial, motor control and automotive applications that require the high-performance and real-time control provided by NEC Electronics' V850™ microcontrollers (MCUs). Targeted for NEC Electronics' V850 microcontroller, this solution integrates Green Hills Software's MULTI® Integrated Development Environment (IDE), which supports multiple language development and debugging, with The MathWorks' Simulink®, Stateflow® and Real-Time Workshop® Embedded Coder, products for modeling, simulation and code generation. The combined solution can be used with both V850 hardware and simulation targets. A demonstration of the embedded software development solution will be shown at NEC Electronics America's booth (#1118) and at Green Hills Software's booth (#1513) at electronicaUSA /Embedded Systems Conference from March 30-April 1 at the Moscone Convention Center in San Francisco.

Embedded software developers use model-based design with Simulink and Stateflow to simulate and optimize their models and automatically generate efficient code with Real-Time Workshop Embedded Coder. However, they still face compilation, optimization, debugging, and verification issues as code is migrated to an embedded target, such as a V850 MCU, and verify its behavior. For example, developers must define compiler settings and build rules, optimize program hot spots, debug divergences between model and hardware, initialize and control the target board and debug the underlying operating system without the use of the original model. The integrated software solution addresses these issues through a co-simulation/co-verification solution that reduces the time

needed to implement code generated from models onto hardware and complete their verification. "By combining Green Hills' MULTI IDE with The MathWorks Simulink model-based design platform, we have integrated a complete solution that allows developers working with our V850 MCU products to quickly and more efficiently connect, compile, test and debug their programs," said Bart Ladd, general manager, microcontroller strategic business unit, NEC Electronics America. "Developers can use the Simulink and Stateflow model view of their application through all stages, from design through development, debugging and deployment. This reduces the verification and debug run-time required by the state-driven modeling systems typically associated with motor- or process-control industrial applications."

"Developers working with embedded applications, particularly those in the industrial and automotive space, require quick, accurate and efficient methods of moving their embedded-software designs through the simulation, implementation and verification phases to the deployment phase," said David Kleidermacher, vice president of engineering, Green Hills Software. "Through this partnership, we are able to provide developers with an integrated, high-performance solution based on proven technology from three leading suppliers of model-based design tools, software development tools and embedded MCUs."

"Developing and debugging at the model level is a strength of The MathWorks products, and Green Hills provides equally strong capability for code running on the target. However, developers also want to use insight gained from the model's execution while verifying the automatically generated code running on the target," said Jim Tung, MathWorks Fellow, The MathWorks, Inc. "This new integrated software solution enables developers using Simulink with Green Hills' MULTI IDE to streamline the debugging and verification process by allowing them access to both tool sets simultaneously, running the Simulink models and MULTI C code equivalents together at the block level, rather than requiring them to port projects back and forth between the two environments."
