Method for analyzing sensitivity and failure probability of a circuit

摘要

A method, implemented in a processor, of determining a likelihood of failure of a circuit to be made in accordance with a circuit design, and a computer-readable storage medium storing instructions to the processor for carrying out the method. A sensitivity of a figure of merit to each variable of a plurality of variables is determined by simulating operation of the circuit using the processor. Determining the sensitivity is based on a departure of each of the variables from a respective mean value, where the variables include at least one variable derived from measurements of a fabricated component or component combination to be included in the circuit. Results from the simulation are used to predict a failure probability of the circuit to be made in accordance with the circuit design.
