Sut tool

If no real SUT is available you can simulate an SUT from a state machine model using the Sut tool. We employ the UPPAAL GUI to specify SUTs. For example :

Example model of the alternating bit protocol receiver
Figure 2: Example model of the alternating bit protocol receiver

Using the Sut tool we can easily generate a running SUT from the above model. Note that we can only learn a restricted class of extended finite state machines (EFSM), i.e. Scalarset Mealy machines. For details on the restrictions, please study the Making Your Own SUT page and our paper "Automata Learning Through Counterexample-Guided Abstraction Refinement" [CEGAR12].
