Resumé

We present an extension of the model checker Uppaal capable
of synthesizing linear parameter constraints for the correctness of
parametric timed automata. The symbolic representation of the (parametric)
state-space is shown to be correct. A second contribution of this
paper is the identification of a subclass of parametric timed automata
(L/U automata), for which the emptiness problem is decidable, contrary
to the full class where it is know to be undecidable. Also we present a
number of lemmas enabling the verification effort to be reduced for L/U
automata in some cases. We illustrate our approach by deriving linear
parameter constraints for a number of well-known case studies from the
literature (exhibiting a flaw in a published paper).
