RTE Generation and BSW Configuration Tool-Extension for Embedded Automotive Systems

Automotive embedded systems have become very complex, are strongly integrated and the safety-criticality and real-time constraints of these systems are raising new challenges. Distributed system development, short time-to-market intervals, and automotive safety standards (such as ISO26262) require efficient and consistent product development along the entire development lifecycle. The challenge, however, is to ensure consistency of the concept constraints and configurations along the entire product life cycle. So far, existing solutions are still frequently insufficient when transforming system models with a higher level of abstraction to more concrete engineering models (such as software engineering models).


The aim of this work is to present a model-driven system-engineering framework addon, which enables the configurations of basic software components and the generation of a runtime environment layer (RTE; interface between application and basic software) for embedded automotive system, consistent with preexisting constraints and system descriptions. With this aim in mind a tool bridge to seamlessly transfer artifacts from system development level to software development level is described. This enables the seamless description of automotive software and software module configurations, from system level requirements to software implementation and therefore ensures both consistency and correctness for the configuration.
