Abstract

Graded-CTL is an extension of CTL with graded quantifiers which allow to reason about either at least or all but any number of possible futures In this paper we show an extension of the NuSMV model-checker implementing symbolic algorithms for graded-CTL model checking The implementation is based on the CUDD library, for BDDs and ADDs manipulation, and includes also an efficient algorithm for multiple counterexamples generation.
