Formal Verification of UML Statecharts with Real-Time Extensions

  title={Formal Verification of UML Statecharts with Real-Time Extensions},
  author={Alexandre David and M. Oliver M{\"o}ller and Wang Yi},
We present a framework for formal verification of a realtime extension of UML statecharts. For clarity, we restrict ourselves to a reasonable subset of the rich UML statechart model and extend this with real-time constructs (clocks, timed guards, and invariants). We equip the obtained formalism, called hierarchical timed automata (HTA), with an operational semantics. We outline a translation of one HTA to a network of flat timed automata, that can serve as input to the real-time model checking… CONTINUE READING
