Abstract

Proper modeling of switching windows leads to a better estimate of the noise-induced delay variations. In this paper, we propose a new non-iterative continuous switching model. The proposed new model employs an ordering technique combined with the principle of superposition of linear circuits. The principle of superposition considers the impact of aggressors one after the other. The ordering technique avoids convergence and multiple solution issues in many practical cases. Our model surpasses the accuracy of the traditional discrete model and the speed of fixed point iteration method.
