PYFS-a statistical optimization method for integrated circuit yield enhancement

An efficient optimization method for the statistical design of integrated circuits is presented. This method, called the pseudo yield function substitution (PYFS) algorithm, is developed to help a designer select design parameters to maximize the product yield. The design goal of PYFS is to use fewer simulation runs to reach a yield-optimized design. This is accomplished with the development of an improved response surface method for accurate estimation of the circuit response function, and the use of a novel PYFS method for yield maximization.<
