Managing complexity and variability of a model-based embedded software product line


This paper presents a framework for model-based product lines of embedded systems. We show how to integrate model-based product line techniques into a consistent framework that can deal with large product lines as they are common in industry. The framework demonstrates the strengths of model-based techniques like abstraction, support for customised representations, and a high degree of automation. In particular, we provide the following contributions: (1) to shift existing product lines towards a model-based approach, we support the (semi-) automated extraction of models from existing requirement, test, and implementation artefacts; (2) to cope with the complexity of artefacts and their interrelations in industrial product lines, we support the generation of context-specific views. These views support developers, e.g., in analysing complex dependencies between different artefacts; (3) finally, we support automated product derivation based on an integrated hardware abstraction layer. Most of the presented concepts have been inspired by challenges arising in the industrial application of product line techniques in the model-based engineering of embedded systems. We report on experiences gathered during the application of the techniques to a prototypical product line (on a rapid prototyping platform in the university lab) and to industrial sample cases (at the industry partner).
