EMFtoCSP: a tool for the lightweight verification of EMF models

The increasing popularity of MDE results in the creation of larger models and model transformations, hence converting the specification of MDE artefacts in an error-prone task. Therefore, mechanisms to ensure quality and absence of errors in models are needed to assure the reliability of the MDE-based development process. Formal methods have proven their worth in the verification of software and hardware systems. However, the adoption of formal methods as a valid alternative to ensure model correctness is compromised for the inner complexity of the problem. To circumvent this complexity, it is common to impose limitations such as reducing the type of constructs that can appear in the model, or turning the verification process from automatic into user assisted. Since we consider these limitations to be counterproductive for the adoption of formal methods, in this paper we present EMFtoCSP, a new tool for the fully automatic, decidable and expressive verification of EMF models that uses constraint logic programming as the underlying formalism.
