Abstract

Two methods are described here for Computer-Aided Design (CAD) programs that compute sensitivities and perform optimization: (a) Computing sensitivities with respect to arbitrary type or design parameters, especially those that occur in complicated expressions in integrated circuitry. (b) An efficient technique to compute the gradient of an objective function in time-domain optimization. where this technique avoids the excessive storage requirement of the adjoint method. Sensitivity Computations:
