a new method towards achieving global optimality in technology mapping
This paper presents a new method for covering a Boolean network by library cells. In this method, matches are classified according to their properties. Some matches are selected unconditionally into a cover and the remaining nodes are divided into independent portions. Then, a match compatibility graph (MCG) is constructed for each portion and an optimum cover is found for it using the MCG. Thus, our method finds an efficient and closer to optimum cover for the complete network.
