A method for determining criticality probability of an edge of a timing graph of a circuit is described. The method includes forming a directed acyclic timing graph corresponding to a circuit being timed, performing statistical timing of the circuit, for each edge of interest, defining a cutset that divides the timing graph into a plurality of parts, determining an edge slack for each edge in the cutset, computing a statistical maximum of all edge slacks in the cutset, and inferring edge criticality probabilities of each edge from the statistical maximum. A system for determining criticality probability of an edge of a timing graph of a circuit is also described.
