We describe a fast (linear time) procedure to optimally size transistors in a chain of multi-input gates/stages. The fast sizing is used in a simultaneous sizing and restructuring optimization procedure, to accurately predict relative optimal performance of alternative circuit structures for a given total area. The idea extends the concept of optimally sizing a buffer chain, and uses tapering constants based on the position of a stage in a circuit, and the position of a transistor in a stack.
