ULM Implicants for Minimization of Univers Logic Module Circuits

In this paper a method is developed for circuit minimization using the universal logic modules (ULM's) of Yau and Tang. This objective is obtained by using an extension of prime implicants termed ULM implicants. Each ULM implicant implies one possible saving of a module in the tree structure implementing a function. The method is developed for the ULM(l) and an extension to the higher order ULM(p) is discussed.
