Automated Analysis of Multi-View Software Architectures

Abstract: Software architectures usually are comprised of different views for capturing static, runtime, and deployment aspects. What is currently missing, however, are formal validation and verification techniques of multi-view architecture in very early phases of the software development lifecycle. The main contribution of this paper therefore is the construction of a single formal model (in Promela) for certain stylized, and widely used, multi-view architectures by suitably interpreting and fusing sub-models from different UML diagrams. Possible counter-examples produced by model checking are fed back as test scenarios for debugging the multi-view architectural model. We have implemented this algorithm as a plug-in for the Enterprise Architect development tool, and successfully used SPIN model checking for debugging some industrial architectural multi-view models by identifying a number of undesirable corner cases.
