Hardware architecture exploration: automatic exploration of distributed automotive hardware architectures

abstract

As the engineering of distributed embedded systems is getting more and more complex, due to increasingly sophisticated functionalities demanding more and more powerful hardware, model-based development of software-intensive embedded systems has become a de facto standard in recent years. Among other advantages, it enables design space exploration methods allowing for frontloading techniques which support a system architect already at early stages of development. In this paper, we want to present an approach which is capable of automatically generating automotive E/E architectures (electric/electronic architecture; in-car network of processing units and buses). Based on the concept of viewpoints, we will introduce dedicated technical meta-models, a language to formally describe a hardware architecture exploration problem and an automatic exploration approach using satisfiability modulo theories. We will furthermore introduce a dedicated methodology and show how an exploration integrates into a system development process. In the end, we will evaluate our approach by applying it to an industrial use case provided by Continental.
