Settling time modeling of the ground bounce produced into the switching buffer

This paper presents a macromodel for modeling the ground bounce produced by the buffer in switching state. The timing macromodel used to implement this technique is up to several times faster than Spice2 and up to several times faster than existing nonlinear macromodels. The accuracy of this macromodel over a wide range of operating conditions is demonstrated. The macromodel can be used to minimize VLSI simulation time, and generate data for high-level macromodels.
