In this paper a method is presented for reducing the number of stages of logic in the realization of an arbitrary Boolean function when an upper bound exists on the fan-in at each gate. A procedure for obtaining the minimum stage realization of the function in sum of products form is first developed. The use of factoring to reduce the number of stages below this minimum is then described.
