A method for identifying instances of a smaller circuit in a larger circuit is provided. Both the smaller circuit and the larger circuit have a plurality of vertices. A vertex is one of a device or a net. The device, such a transistor, includes a Gate, a Drain, and a Source. The net is a wired connection between devices. The method includes recursively relabeling of each of the plurality of vertices until labels of all neighboring vertices of a selected vertex are zero. The neighboring vertices of a vertex are vertices that are directly connected to the vertex. Each successive iteration of the relabeling uses labels of each of the plurality of vertices after a previous iteration of the relabeling. Then, a recursive circuit tracing operation is performed.
