Abstract: PROBLEM TO BE SOLVED: To provide a method and a structure which reduces power consumption on a microelectronic circuit. SOLUTION: This method distinguishes at least one wiring pair including the first wiring and the second wiring. The second wiring is already tristated or tristatable. The wiring pair has same directional probability over the prescribed or the user selected minimum same directional switching availability for one clock cycle. Or, the wiring pair has opposite directional probability over the prescribed or the user selected minimum opposite directional switching availability for one clock cycle. The first and the second wiring satisfies at least one mathematical relation, and this mathematical relation includes distance between the first and the second wiring, and common run length of the first and the second wiring.
