Abstract

The main contribution of the paper consists in showing that the bounded model checking (BMC) method is feasible for ACTLS* (the universal fragment of CTLS*) which subsumes both ACTL and LTL. The extension to ACTLS^* is obtained by redefining the function returning the sufficient number of executions over which an ACTLS* formula is checked, and then combining the two known translations to SAT for ACTL and LTL formulas. The proposed translation of ACTLS* formulas is essentially different from the existing translations of both ACTL and LTL formulas. Moreover, the formal treatment is the basis for the implementation of the technique in the symbolic model checker √erics.
