Patent ID: 6901570

Claim:
A method for generating optimum skew corners for a compact device model, comprising the steps of: collecting a number N of multiple performance targets F i , wherein i=1, 2, . . . N; identifying a number M of model parameters to be included in a skew corner analysis, and for each model parameter its tolerance and its nominal value in the compact device model; for each said performance target F i , doing a sensitivity analysis and finding N sensitivity coefficients a ij , wherein J=1, 2, . . . , M; for each said performance target F i , setting a sign and value of a parameter η i for a skew corner case to η i =1 if a value of the target F i increases in the skew corner case and to η i =−1 if the value of the target F i decreases in the skew corner case; classifying performance targets into groups; for each group, comparing the number of targets N in the group and its relation to the number of model parameters M; and for each group, calculating a skew corner coordinate based on the relationship between the number of targets N and the number of model parameters M.
