Direct Model-checking of SysML Models

Model-checking intends to verify whether a property is satisfied by a model, or not. Model-checking of high-level models, e.g. SysML models, usually first requires a model transformation to a low level formal specification. The present papers proposes a new model-checker that can be applied (almost) directly to the SysML model. The paper first explains how this model-checker works. Then, we explain how it can efficiently check CTL-like properties. Finally, the paper discusses the performance of this model-checker integrated in the TTool framework.
