Automated Check of Architectural Models Consistency Using SPIN

Abstract

In recent years the necessity for handling different aspects of the system separately has introduced the need to represent SA (software architectures) from different viewpoints. In particular, behavioral views are recognized to be one of the most attractive features in the SA description, and in practical contexts, state diagrams and scenarios are the most widely used tools to model this view. Although very expressive, this approach has two drawbacks: system specification incompleteness and view consistency. Our work can be put in this context with the aim of managing incompleteness and checking view conformance: we propose the use of state diagrams and scenario models for representing system dynamics at the architectural level; they can be incomplete and we want to prove that they describe, from different viewpoints, the same system behavior. To reach this goal, we use the SPIN model checker and we implement a tool to manage the translation of architectural models in Promela and LTL.
