TCTL model checking
· Model checking timed automata against TCTL is decidable
­ example TCTL-formula: 3 10
goal
· Key ingredient for decidability: finite quotient wrt. a bisimulation
­ bisimulation = equivalence on clock valuations
­ equivalence classes are called regions
· Region automaton is highly impractical for tool implementation
­ the number of regions lies in (|C|!·
