Embedded software and electronics represent an increasing percentage of the engineering content of an automobile. By 2010, electronics are expected to comprise 40 percent of automotive material costs, up from 10 percent in 1970 [1]. Embedded software and electronics are used across the car's functional areas, replacing or simplifying mechanical and hydraulic systems in core functions, such as steering and braking, and implementing advanced features, such as active safety systems and driver information systems, that add significant customer value in terms of convenience, comfort, and safety.
However, the rapid growth in complexity of embedded software and electronics coupled with the difficulty of testing and verifying these systems has been associated with a rise in quality issues and recalls. According to IBM Corporation, automakers spend two to three billion dollars a year to fix software problems and 32 percent of auto warranty claims in the United States are for software- or electronics-related issues.
Model-Based Design has become the preferred approach for developing automotive embedded software because it improves the specification, design, and implementation phases. Now, new tools and capabilities are available for Model-Based Design that help address test and verification challenges, improving embedded software quality and shortening the test and verification cycle.
