  • Patent number: 10726190
    Abstract: Systems and methods are provided for identifying a wire of a plurality of wires to be adjusted to mitigate effects of electromigration. A segment electromigration stress value for each segment of a wire is determined for a wire of a circuit in a circuit design. A wire electromigration stress value for the wire is determined as a function of the segment electromigration stress values of segments of the wire. A ranked list of two or more wires of the circuit is displayed according the wire electromigration stress values of the two or more wires.

  • Patent number: 10181004
    Abstract: Systems and methods are provided for identifying a wire of a plurality of wires to be adjusted to mitigate effects of electromigration. A method includes identifying a plurality of wires of a circuit, each wire comprising a one or more wire segments. An electromigration stress is determined for each wire path of each wire, a wire path being made up of one or more wire segments. For each wire, a highest determined electromigration stress is assigned for wire paths of that wire as the wire electromigration stress for that wire. An identification of the wire having the highest wire electromigration stress is stored, where the wire having the highest wire electromigration stress is a candidate for adjustment to mitigate electromigration effects.

  • Publication number: 20080265725
    Abstract: There is provided a cart and method for manufacturing wood furniture assemblies, such as wood frames for couches and other upholstered furniture. The method includes cutting stock wood at a cutting location to predetermined dimensions to form wood frame members of a plurality of different configurations. A plurality of kits of the wood frame members are selectively disposed on a wheeled cart at the cutting location, each kit including each of a plurality of wood frame members for assembling one furniture frame assembly. The cart is then transported with the kits of the wood frame members to an assembly location remote from the cutting location. The cart can generally include first and second cargo portions that are supported by a wheeled support frame. The cargo portions define horizontal and vertical compartments for receiving all of the wood frame members for assembling a plurality of the wood furniture frame assemblies.
