Abstract:
1. A method implemented by an appropriately programmed computer for determining specifications of an electronic system or integrated circuit product which satisfy quality, reliability and cost requirements, comprising: a. acquiring data from a test vehicle, wherein said test vehicle comprises at least one electronic component of an integrated circuit product, wherein said acquired data comprises at least one attribute value of said electronic component for a plurality of physical instances or a plurality of simulated instances of said test vehicle determined at one or more environmental conditions and one or more o eratin conditions wherein said plurality of physical instances or said plurality of simulated instances comprises a sample of a population of said instances; b. fitting a copula-based statistical model using said appropriately programmed computer to said acquired data, wherein said copula-based statistical model comprises marginal distributions of said acquired data and a copula for each said at least one electronic component of said test vehicle, wherein said fitting comprises determination of a desired form of said marginal distributions of said acquired data and a desired form of said copula, wherein said desired form of said copula embodies a flexibility to represent a statistical tail dependency of said data, wherein said fitting comprises: c. using said fitted copula-based statistical model to compute probabilities of passing a test manufacturing operation (Test) and failing in end use (Use) for said product wherein said probabilities are used to compute figures of merit wherein said figures of merit are compared with target values of said figures of merit to determine whether the product satisfies product specifications, wherein said product specifications comprise a product design specification, a test manufacturing specification, and a product datasheet specification, wherein said product design specification comprises fault tolerance requirements, wherein test manufacturing specification comprises:
