Abstract
Formal analysis of models is an important aspect of the Model Driven Development (MDD) paradigm. In this paper we introduce a technique to analyze models with hierarchically organized and asynchronously communicating components as found in, e.g., UML-RT. Typically, the more components are composed during analysis, the less scalable it becomes. In our technique we reduce composition by leveraging the communication topology and the property to be checked. To this end we introduce an extension of Computation Tree Logic (CTL) to express properties of models and we show an algorithm to check such properties. In the algorithm, components are represented by their symbolic execution trees and their composition is lazy, i.e., only performed when necessary. To demonstrate some of the benefits of the technique, its implementation for UML-RT models and case studies are discussed.
