ABSTRACT

In this chapter, using only AND and OR gates, we will synthesize a two-level logic network. This is the fastest network, if we assume that every gate has the same delay, since the number of levels cannot be reduced further unless a given function can be realized with a single AND or OR gate. If there is more than one such network, we will derive the simplest network. Such a network has a close relation to important concepts in switching algebra, that is, irredundant disjunctive forms and minimal disjunctive forms (or minimal sums), as we discuss in the following.
