摘要： An electrical wiring structure and a computer system for designing the electrical wiring structure. The electrical wiring structure includes a wire pair. The wire pair includes a first wire and a second wire. The second wire is slated for being tri-stated. The wire pair has 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 has an opposite-direction switching probability φOD per clock cycle that is no less than a pre-selected minimum opposite-direction switching probability φOD,MIN. The first wire and the second wire satisfies at least one mathematical relationship involving LCOMMON and WSPACING, where WSPACING is defined as a spacing between the first wire and the second wire, and LCOMMON is defined as a common run length of the first wire and the second wire.

摘要： An electrical wiring structure and method of designing thereof. The method identifies at least one wire pair having a first wire and a second wire. The second wire is already tri-stated or can be tri-stated. The wire pair may have a same-direction switching probability per clock cycle that is no less than a predetermined or user-selected minimum same-direction switching probability. Alternatively, the wire pair may have an opposite-direction switching probability per clock cycle that is no less than a predetermined or user-selected minimum opposite-direction switching probability. The first wire and the second wire satisfy at least one mathematical relationship involving: a spacing between the first wire and the second wire; and a common run length of the first wire and the second wire.
