The present invention is directed to clock domain conflict analysis of a timing graph that features, dissociating clock domains of one or more of a path having conflicting clock domains while preserving the original clock domain relationship of the edges in the path. To that end, the method includes generating a timing graph having a source instance, a destination instance and a plurality of edges defining a plurality of signal paths between the source instance and the destination instance. A plurality of clock domains is corresponded to the timing graph, with a subset of the plurality of edges being associated with more than one clock domain. From the subset, conflicting clock domains associated with a common edge are identified. In response to identification of the conflict, one of the clock domains is dissociated from one of the edges of the subset.
