Extended Architecture Analysis Description Language for Software Product Line Approach in Embedded Systems

Describing architecture variabilities explicitly and precisely is important in the software product line approach for software development since it helps product derivation as well as modeling and managing the variabilities. The SAE AADL is an industry standard architecture analysis and design language for the automotive community, which originally was not intended to be used for software product line. In this paper, we propose EAADL a software product line architecture description language for the automotive domain that extends the SAE AADL. By incorporating orthogonal variability model into it, EAADL offers traceability with requirement engineering as well as the implementation process that is essential in software product line engineering.
