Experimental Study of A Novel Variant of Fiduccia Mattheyses(FM) Partitioning Algorithm

Partitioning is a well studied research problem in the area of VLSI physical design automation. In this problem, input is an integrated circuit and output is a set of almost equal disjoint blocks. The main objective of partitioning is to assign the components of circuit to blocks in order to minimize the numbers of inter-block connections. A partitioning algorithm using hypergraph was proposed by Fiduccia and Mattheyses with linear time complexity which has been popularly known as FM algorithm. Most of the hypergraph based partitioning algorithms proposed in the literature are variants of FM algorithm. In this paper, we have proposed a novel variant of FM algorithm by using pair wise swapping technique. We have performed a comparative experimental study of FM algorithm and our proposed algorithm using two dataset such as ISPD98 and ISPD99. Experimental results show that performance of our proposed algorithm is better than the FM algorithm using the above dataset.
