Model based Approach for Automotive Embedded Systems

Abstract

This paper discusses the use of Model based Development to accelerate development process of embedded control systems and technologies and tools used to support model-based development (MBD) from functional requirements to automated testing and Model based testing process. In past few decades automotive embedded systems are transformed from an electrical mechanical engineering discipline to a combination of software and electrical/ mechanical engineering. This evolution establishes software as a crucial technology. Growth of embedded software has led to more complex systems with multiple electronic control units of different characteristics in today’s vehicle. As a result, automotive industry focuses on a new trend Model based development rather than traditional method where software is handwritten in Assembly code or C language. However, quality assurance is important factor throughout the development process and testing is a key element for quality assurance.
