The incorporation of timing makes circuit verification computationally expensive. This paper proposes a new approach for the verification of timed circuits. Rather than calculating the exact timed stare space, a conservative overestimation that fulfills the property under verification is derived. Timing analysis with absolute delays is efficiently performed at the level of event structures and transformed into a set of relative timing constraints. With this approach, conventional symbolic techniques for reachability analysis can be efficiently combined with timing analysis. Moreover the set of timing constraints used to prove the correctness of the circuit can also be reported for backannotation purposes. Some preliminary results obtained by a naive implementation of the approach show that systems with more than 10/sup 6/ untimed states can be verified.
