Integration and Analysis of Design Artefacts in Embedded Software Development

In model-based development of embedded software product lines, artefacts, i. e. the requirements document, implementation model, and tests, often become extremely complex w. r. t. size and dependencies. Moreover, the interrelationships among the artefacts are not obvious and information about development, design decisions as well as variability-related aspects are missing. Hence, engineers have to thoroughly analyse such dependencies to incorporate changes during evolution of the product (line) to assure quality. As this task is time-intensive and error-prone such analysis efforts have to be automated. This paper presents a comprehensive and extensible framework under development which provides (1) artefact integration and (2) analysis functionality to address these issues by following an approach based on a central database.
