MDE 2.0 : Pragmatical formal model verification and other challenges

This document presents a synthesis of the research results conducted in the eld of software veri cation for model-driven engineering (MDE). MDE is becoming one of the dominant software engineering paradigms in the industry. The main characteristic of MDE is the use of software models and model manipulation operations as main artifacts in all software engineering activities. This change of perspective implies that correctness of models (and model manipulation operations) becomes a key factor in the quality of the nal software product. The problem of ensuring software correctness is still considered to be a Grand Challenge for the software engineering community. At the modellevel, we are still missing a set of tools and methods that helps in the detection of defects and smoothly integrates in existing MDE-based tool-chains without an excessive overhead. Characteristics of existing tools, which require designer interaction, deep knowledge of formal methods or extensive manual model annotations seriously impair its usability in practice. In this document, we present our pragmatic set of techniques for formal model veri cation to overcome these limitations. We call our techniques pragmatic because they try to nd the best trade-o between completeness of the veri cation and the usability of the process.
