UML-B

Return to Rodin Plug-ins

UML-B provides a 'UML-like' graphical front end for Event-B. It provides various diagrammatic modelling notations and editors for creating models which are then translated into Event-B for verification. UML-B works alongside Event-B allowing the modeller to model in normal Event-B but also contribute some aspects of the model via diagrams.

Our UML-B website contains more information about installing UML-B and getting started, as well as our current research and collaborations.

UML-B is a collection of diagrammatic editors for Event-B. The diagrams are used to elaborate the machine and its content with extra model features. The diagrams may either by contained within the machine they contribute to, or can be contained in a separate UML-B model file that is linked to the machine.

• State-machine diagrams a hierarchical state-machine diagram editor which can be used to impose sequential ordering to your events. An animator is also provided to visualise the progress of the state-machine.

• Class diagrams a class diagram editor which can be used to define data entities and their relationships and to lift behaviour based on data sets.
