Wiring optimizations for power

An electrical wiring structure, comprising at least one wire pair, said wire pair including a first wire and a second wire, said second wire slated for being tri-stated, said wire pair having a same-direction switching probability φSD per clock cycle that is no less than a pre-selected minimum same-direction switching probability φSD,MIN or having an opposite-direction switching probability φOD per clock cycle that is no less than a pre-selected minimum opposite-direction switching probability φOD,MIN, said first wire and said second wire satisfying at least one mathematical relationship, said at least one mathematical relationship involving LCOMMON and WSPACING, said WSPACING defined as a spacing between the first wire and the second wire, said LCOMMON defined as a common run length of the first wire and the second wire.

An electrical wire structure, comprising two wires of a wire network, said two wires denoted as an A wire and a B wire, said A wire having a capacitance CA, said B wire having a capacitance CB, said A wire and B wire having a coupling capacitance CC between the A wire and the B wire, said B wire in a tri-state, said A wire transitioning from a voltage VA1 to a voltage VA2 such that VA2≠VA1, said B wire having transitioned to the tri-state from a voltage VB1, said B wire intended to be transitioned to a voltage VB2 such that VB2≠VB1 after the A wire has transitioned to the voltage VA2, said transition of the A wire from the voltage VA1 to the voltage VA2 and of the B wire from the voltage VB1 to the voltage VB2 identified as a two-wire voltage transition.

A computer program product, comprising:

• a computer usable medium having a computer readable program code embodied therein for designing an electrical wiring structure having a plurality of wires, wherein the computer readable program code includes an algorithm, said algorithm identifying at least one wire pair, said wire pair including a first wire of the plurality of wires and a second wire of the plurality of wires, said second wire already tri-stated or can be tri-stated, said wire pair having a same-direction switching probability φSD per clock cycle that is no less than a pre-selected minimum same-direction switching probability φSD,MIN or having an opposite-direction switching probability φOD per clock cycle that is no less than a pre-selected minimum opposite-direction switching probability φOD,MIN, said first wire and said second wire satisfying at least one mathematical relationship, said at least one mathematical relationship involving LCOMMON and WSPACING, said WSPACING defined as a spacing between the first wire and the second wire, said LCOMMON defined as a common run length of the first wire and the second wire.
