Logic replication has been shown to be very effective in reducing the number of cut nets in partitioned circuits. Liu et al. in considered the circuit partitioning problem with logic replication for separating two given nodes and presented an algorithm to determine a partitioning of the minimum possible cut size. In general, there are many possible partitioning solutions with the minimum cut size and the difference of their required amounts of replication can be significant. Since there is a size constraint on each component of the partitioning in practice, it is desirable to also minimize the amount of replication. In this paper, we present a network-flow based algorithm to determine an optimum replication min-cut partitioning that requires minimum replication. And we show that the algorithm can be generalized to separate two given subsets of nodes and determine an optimum partitioning of the minimum possible cut size using the least possible amount of replication. We also show that our algorithm can be used to improve the solutions produced by any heuristic replication min-cut partitioning algorithm by reducing the cut size and shrinking the replication set.
