A Systematic Procedure for the Generation of Cost-Minimized Designs

Abstract
We present a procedure for the generation of cost-minimized designs of circuits and systems. Suppose a designer has decided upon the topology of his product. Also suppose he knows the cost and quality of the different grades of the N components required to implement the product. The designer then faces the following problem: How should he proceed to find the combination of grades that will give him the desired manufacturing yield at minimum product cost? We discuss the problem and suggest a policy by which the designer, with a reasonable computational effort, can find a set of ``good'' implementations. The suggested policy is applied to an electronic amplifier. The results are quite encouraging.
