Abstract:
1. A method to optimize a multi-parameter design (MPD) having design variables and performance metrics, the method comprising steps of: a) calculating, at a first set of design corners, by using a computer, a performance value of each performance metric for each candidate design of a first set of candidate designs, each performance metric being a function of at least one of the design variables, the design variables defining a design variables space, the MPD having associated thereto the first set of candidate designs, random variables, defining a random variables space, and environmental variables, defining an environmental variables space, the random variables space and the environmental variables space defining design corners at which the candidate designs can be evaluated, each candidate design representing a combination of design variables; b) calculating, for each performance value, by using the computer, a performance value uncertainty, the performance value of each performance metric for each candidate design of the first set of candidate designs, and its respective performance value uncertainty, defining a first set of data; c) in accordance with the first set of data, building a model of each performance metric to obtain a first set of models, each model mapping at least one design variable to a model output and to a model output uncertainty; d) storing the first set of models in a characterization database; e) displaying, for selection, one or more models of the first set of models, and their model uncertainty; f) in response to a selection of one or more candidate designs, which defines selected candidate designs, and in accordance with the one or more displayed models: and g) displaying, for inspection, one or more models of the third set of models.
