Dealing with Variability in Architecture Descriptions to Sup- port Automotive Product Lines: Specification and Analysis Methods

Architectural description languages (ADLs) are essential means for a system and software design in the large. Their common concepts are components, ports, interfaces and connectors. Some of them already support the representation and management of variance, a prerequisite to support product line engineering, but the support of variability often stops on component level. In this paper, a more detailed view on the integration of variability into architectural models concerning the formal analysis of variability and the related assessment of the defined product lines is taken. The focus is set on the support of product line engineering within the automotive E/E domain, where functionality or its realization is varying according to specific customer needs and hardware topologies. In general, the fundamental question in this domain is not, if a product line approach is applied, but what is the best way to integrate it.
