Model based software development – solutions for series software

The claim for fast and efficient implementation of functional requirements grows as fast as the complexity of the systems. To cope with these requirements and allow early availability of software, model based methods of software development for embedded systems have been established. Of course these methods influence the whole development process of the software. To answer the question, if model based software development has additional benefits we need a common concept, covering all phases of developing process. By using the example of electric transmission development we show tools and processes used by ZF in this lecture. It makes efficient work possible throughout the whole development process. Quality is mentioned mainly because safety functions are model based as well. The base is a strong orientation on the process attended by quality assurance. To control the growing complexity ZF additional makes use of reuse. This brings a further challenge to model based software development.
