For SPICE level circuit development, corner models address the designer’s need for fast simulations which can reproduce specific scenarios of interest. To systematically and automatically determine the model parameters for the corners, we present a methodology based on a constrained least squares optimization. We also show how it performs when applied to some of our devices for best and worst case scenarios. Keywords — spice simulation; corner modeling; least squares optimization
