Abstract : The article analyzes the methods of statistical design and applies them, for illustration, to the example of a digital circuit. The problems of random effects on the performance and the problems of parameter tolerances are discussed first. A random quantity is defined and its characteristics are shown in a mathematical form. Both the moments method and Monte Carlo method of determining the distribution functions of random quantities are shown and compared. When used for evaluating the KME/D2 line of logic circuits, these statistical techniques have shown that, after the CONJUNCTION stage, fan-out is possible for two NEGATORS or for a NEGATOR and a NOR. The basic circuit, the approximated density functions, and the results of 400 computation cycles for the worst-case-value are shown. (Author)
