Behavioral model for high-speed digital buffer/driver

This paper presents a new behavioral macromodeling approach for high-speed digital output buffers/drivers. Unlike traditional behavioral black-box modeling techniques, our approach consists of modeling digital drivers based on their physical constitution in order to simplify the complexity of the nonlinear parametric relationship and include the package network within the nonlinear model structure. For that, the operation of the driver was analyzed by dividing the problem into a nonlinear static and a linear dynamic part. The resulting model is useful for the signal integrity (SI) analysis and has a good performance in terms of both accuracy and speed.
