A system and method utilized to receive an integrated circuit (IC) design and generating a graph based on a plurality of sub-circuits of the IC design. Further, one or more candidate sub-circuits are determined from the plurality of sub-circuits based on the graph. Additionally, one or more sub-circuits are identified from the one or more candidate sub-circuits based on a number of transistors and a number of edges within each of the plurality of sub-circuits. An indication of the identified one or more sub-circuits is provided.
