# Synthesis of Timing Parameters Satisfying Safety Properties

@inproceedings{Andr2011SynthesisOT, title={Synthesis of Timing Parameters Satisfying Safety Properties}, author={{\'E}tienne Andr{\'e} and Romain Soulat}, booktitle={RP}, year={2011} }

Safety properties are crucial when verifying real-time concurrent systems. When reasoning parametrically, i.e., with unknown constants, it is of high interest to infer a set of parameter valuations consistent with such safety properties. We present here algorithms based on the inverse method for parametric timed automata: given a reference parameter valuation, it infers a constraint such that, for any valuation satisfying this constraint, the discrete behavior of the system is the same as under…
