US Patent 9292642 Superconducting circuit physical layout system and method

Systems and methods are provided for physical layout of superconductor circuits. The physical layout system and method is configured to place and route the superconducting circuits by first placing the gates in the form of gate tiles within unoccupied areas of a predetermined circuit design based on a netlist. Each gate tile type includes a particular gate type and a plurality of unassigned Josephson junctions that can be employed in the gates and/or the active interconnects. Inductive wires are then routed between gates incorporating and assigning the Josephson junctions to produce active interconnects between the I/O terminals of the gates based on connections defined in the netlist.
