Managing design improvement with statistical tools and computer simulation

This paper outlines the use of new tools in the design of electronics products. The need for the use of these new tools is illustrated with examples of the adverse effects on manufacturing and the penalty of bringing a product late to the market. The new tools are a combination of circuit simulation, which is used to evaluate circuit performance, and statistical tools, such as Monte Carlo simulation, Cp & Cpk measurement, and design centering. The statistical tools are used for evaluating the effect of component tolerances and to optimise the design.
