COmputing MInimal CounterexamleS for Discrete-Time Markov Chains
COMICS is a stand-alone tool which performs model checking and the generation of counterexamples for discrete-time Markov Chains (DTMCs). For an input DTMC COMICS computes an abstract system that carries the model checking information and uses this result to compute a critical subsystem, which induces a counterexample. This abstract subsystem can be refined and concretized hierarchically. The tool comes with a command line version as well as a graphical user interface which allows the user to interactively influence the refinement process of the counterexample.
