An integrated circuit design tool includes a cell library. The cell library includes entries for a plurality of cells, entries in the cell library including specifications of particular cells in a computer executable language. At least one entry in the cell library can comprise a specification of physical structures and timing parameters of a circuit including a first transistor, a second transistor, and an interconnect connecting a terminal of the first transistor to a terminal of the second transistor, the interconnect comprising one or more nanowires or 2D material strips arranged in parallel. An integrated circuit including the circuit is described.
