We focus on checking safety properties in networks of extended timed automata, with the well-known UPPAAL system. We show how to use predicate abstraction, in the sense used in model checking, to generate search guidance, in the sense used in Artificial Intelligence (AI). This contributes another family of heuristic functions to the growing body of work on directed model checking. The overall methodology follows the pattern database approach from AI: the abstract state space is exhaustivelydoi:10.1007/978-3-540-74128-2_4 fatcat:kcaortt4t5f4rn7omtx5z7cita
