With this paper the model based development environment based on Matlab / Simulink / Stateflow as used at Siemens VDO Automotive AG, Division Powertrain has been presented. The introduction of the model based development environment at SV P has been motivated by 3 topics: Reduction of development cycles and time to market; Possibility of enhanced documentation; Usage of modelling techniques in general. Using an executable specification with PC based simulation an early testing of the controller strategies without the necessity of manual coding is possible. This decreases the number of development loops between function specification and software coding. Additionally the executable specification in form of a Simulink model can be used as basis for real time simulation on the Rapid Prototyping Unit or for early validation directly in the car. Finally the model can also be used as basis for Automatic Coding and by this reduces the coding effort. Based on the interfaces given by the software development in the Automotive Industry the basic concepts have been discussed. SV P uses a generic and XML-based interface to the Configuration Management that is independent of the proprietary CM system. Together with the introduction of a defined architecture of the executable Simulink model, and the system scheduler, a kind of simulated operating system, a generic solution for a multi-user & multi-project development environment for Matlab/Simulink/Stateflow is available. The development environment allows to easily integrating the working results of different developers with clearly defined and documented execution order. The used concept for model based documentation was presented, including the separation between functional content and textual description. Finally, the identified requirements for the next releases of Simulink have been addressed.
