Abstract
A method of determining the lowest possible number of serial switches in a pull-up plane or a pull-down plane of a network implementing a logic function. The same method may be used in any multi-value function. Also, the method may be used in generating switch networks to be implemented as standard cells implementations of combinational logic cells. The minimum number of switches can also be used as a criterion for technology mapping devoted to automatic cell generation. The method is based on the use of a covering table to derive a sum of products where individual cubes have a minimum literal count.
