Abstract
The present disclosure relates to a computer-based method and apparatus for determining datapath bit slices. A first two-way search is performed between an input vector and an output vector to identify gates in a datapath. A network flow is then constructed including the gates identified, and a min-cost max-flow algorithm is applied to the network flow to derive matching bit pairs between the input vector and the output vector. Next, the datapath bit slices are determined by performing a second two-way search between each of a starting bit in the input vector and an ending bit in the output vector of each of the matching bit pairs.
