Abstract
The method for efficiently providing an optimized fanout network includes the steps of providing a series chain of inverters for driving a number of loads. Each load is assigned to a given location of the inverter chain according to the polarity and the required time of the load. Tree-covering techniques are used in conjunction with dynamic programming to minimize the total area of the fanout chain by selecting and sizing the gates to be used in the fanout chain. With such an arrangement, a minimal area fanout chain which satisfies the timing constraints of each load is provided.
