A Boolean function U( z<inf>1</inf>,...,z<inf>m</inf>) is universal for given n=1 and a set I of variables if it realizes all Boolean functions f(x<inf>1</inf>,..., x<inf>n</inf>) by substituting for each zj a variable of I. Designs of universal Boolean functions for various specifications of I are considered for the practical cases of n<10. Assuming the number m of input terminals as criterion of
Functional standardization, logical design, minterm partitions, modularity, number of terminals, polynomial orbits, universal Boolean functions, universal logic modules (ULM).
