Direct synthesis of mapping circuits

In the context of mapping-based methods for multilevel circuit synthesis, the authors propose a method, called the direct implementation procedure (DIP), to synthesize combinational functions. An algebra is defined in which a set of mappings together with a parallel composition operation can produce arbitrary mappings. The resulting mappings can be easily implemented as macrocells. The DIP procedure is simpler than existing methods, and takes advantage of the property of mappings which produces fanout-free circuits. Thus, simple and easily testable combinational circuits can be synthesized using DIP and a mapping-based strategy such as the goal-oriented method
