The tool Imitator implements the Inverse Method (IM) for Timed Automata (TAs). Given a TA A and a tuple π0 of reference valuations for timings, IM synthesizes a constraint around π0 where A behaves in the same discrete manner. This provides us with a quantitative measure of robustness of the behavior of A around π0. The new version Imitator 2.5 integrates the new features of stopwatches (in addition to standard clocks) and updates (in addition to standard clock resets), as well as powerful algorithmic improvements for state space reduction. These new features make the tool well-suited to analyze the robustness of solutions in several classes of preemptive scheduling problems.
