Abstract
A circuit optimization method in which a set of cost functions are stored for each node that indicate the cost of getting signals to that node and the cost of a gate at that node. By 'cost', is meant some figure of merit, such as: the maximal delay for a signal to arrive at a node G; or the area of the elements needed to produce the signal at node G. These cost functions enable the circuit to be optimized without the need for a pattern library and the pattern matching process that is typical of other optimization processes, such as the DAGON Node Tiling Procedure.
