A novel subcircuit extraction algorithm by recursive identification scheme

To extract subcircuits from a large circuit netlist is an important task that contributes a lot in many fields of computer aided design. In this paper, a novel subcircuit extraction algorithm-DECIDE, based on a recursive graph identification scheme as well as a fast graph construction approach is presented. Cooperating with a proper weighting function that assigns a weighting value to each node, the number of nodes needed to be recognized decreases such that the required run time is reduced significantly. In addition, the proposed algorithm is technology independent and can be applied to handle circuits of any design style.
