This paper presents a tool for debugging behavioural models being analysed using model checking techniques. It consists of three parts: (i) one for handling temporal formulas and behavioural models in order to compute annotated models, (ii) one for visualizing the erroneous part of the model with a specific focus on decision points that make the model to be correct or incorrect, and (iii) one for abstracting counterexamples thus providing an explanation of the source of the bug.
