--- abstract: "Animation is important because it allows the modeller to validate that a model behaves as intended. Visualisation of animations assists the modeller in making this assessment. UML-B is a visual 'front-end' to the Event-B notation and includes a state-machine diagram editor. Here we describe a new plug-in which, using the Pro-B model checker as animation engine, provides animation of UML-B state-machine diagrams. Multiple diagrams can be animated simultaneously so that the behaviour of refinements and/or nested state-machines can be explored.
