Abstract
We propose an abstraction-based method that can be applied to falsify a class of computation tree logic (CTL) specifications that combine invariance and reachability requirements in terms of the discrete state of a hybrid control system. The fragment of CTL that we address is not expressible in ACTLź (which includes LTL). The method involves applying supervisory control to a finite abstraction of the hybrid system to falsify the specification. For the class of systems that we consider, falsification of the specification implies a flaw in the design of the control and automation logic.
