Integrated timing analysis in the model-driven design of automotive systems

Automotive electronic systems integrate steadily increasing number of functions. Model-driven development of such systems enables to handle their complexity. With the integration of software-components and their intricate interactions ensuring the non-functional behavior, like timing, becomes a crucial matter. Timing analysis allows the validation of these properties but is mostly only loosely integrated with the development process. Therefore, we introduce an integrated approach enabling the iterative timing validation of model-driven designs. It consists of a framework comprising an UML modeling tool and a simulation-based timing analysis tool. By integrating the design models with respective analysis models, the development of timing-accurate designs is enabled. With the example of an automotive infotainment case study we show the applicability of our approach.
