Abstract
A method of assigning logic functions to macrocells assures that a maximum number of macrocells are assigned two or more logic functions. A first logic function is assigned to a macrocell without restriction. Rules are then applied to the macrocell to determine whether a second logic function may be assigned to the macrocell, and, if so, whether any restrictions exist on what the second logic function may be.
