Abstract

A method of calculating a crossover current component of dynamic power dissipation at a gate of a CMOS integrated circuit design is operable on a digital computer. The method includes deriving two constants. An effective width is computed for the gate, a transition time is computed at an input of the gate, an activity ratio is determined for the gate, and a load capacitance is computed at an output of the gate. The effective width is multiplied by the activity ratio, the clock rate, and the difference of the first constant multiplied by the transition time and the second constant multiplied by the load capacitance to determine a crossover current component of dynamic power of the gate.
