Abstract
A method for constraint region approximation, design centering and yie ld estimation is introduced. Extreme points of the constraint region a re identified by inscribing into it the largest possible ellipsoid. El lipsoid center is the point that centers the design. Ellipsoidal, poly tope and second order Taylor series approximation schemes to the const raint region are discussed. Accuracy and implementation of the method are outlined. Two examples testing the method are included and applica tions to centering, tolerancing and yield estimation are shown.
