Popis The parameter synthesis problem for timed automata is undecidable in general even for very simple reachability properties. In this paper we introduce restrictions on parameter valuations under which the parameter synthesis problem is decidable for Clock-Aware LTL properties. The investigated bounded integer parameter synthesis problem could be solved using an explicit enumeration of all possible parameter valuations. We propose an alternative symbolic zone-based method for this problem which can result in a faster computation. Our technique adapts the ideas of the automata-based approach to Clock-Aware LTL model checking of timed automata. In order to simplify the explanation of our method, we first introduce a parameter synthesis algorithm for timed automata, then we describe method for checking Clock-Aware LTL properties of timed automata and finally we combine these two methods together to provide general parameter synthesis algorithm for Clock-Aware LTL properties. To demonstrate the usefulness of our approach, we provide experimental evaluation and compare the proposed method with the explicit enumeration technique.
