Abstract
A disclosed integrated circuit logic cell includes a clock input operative to receive a clock input from a clock tree of the integrated circuit, and clocking circuitry, internal to the logic cell, operative to place a plurality of clock nodes, within the logic cell, in a logical off state in response to a predetermined logic state of the logic cell, thereby preventing the clock nodes from toggling during the predetermined logic state of the logic cell. The integrated circuit logic cell includes primary logic circuitry, internal to the logic cell, operatively coupled to the clocking circuitry which is operatively coupled to an input of the primary logic circuitry. The clocking circuitry provides clock outputs operatively coupled to the clock nodes which are within the primary logic circuitry, and is operative to control the clock outputs in response to the predetermined logic state.
