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.
