  • Publication number: 20230153505
    Abstract: Electronic design automation (EDA) of the present disclosure logically places components of the electronic circuitry onto an electronic design real estate to determine an architectural design placement for the electronic circuitry. The EDA evaluates a metaheuristic algorithm starting with an initial placement of components of the electronic circuitry onto the electronic design real estate to provide multiple possible placements for placing these components of the electronic circuitry onto the electronic design real estate. The EDA utilizes the multiple possible placements of the metaheuristic algorithm to train one or more probabilistic functions of a model-based reinforcement learning (RL) algorithm. The EDA evaluates the model-based RL algorithm utilizing the one or more probabilistic functions to determine the architectural design placement.

  • Patent number: 8479387
    Abstract: In a method of manufacturing a three-dimensional (3D) circuit device, conducting circuits are formed on a non-conductive base through electroplating. The non-conductive base, and a circuit pattern section, at least one conducting junction and at least one current-guiding junction provided on the base are formed through double injection molding process. An electrically conductive interface layer is formed on the circuit pattern section and the junctions; and then, metal circuits are formed on the circuit pattern section through electroplating. By providing the conducting junction and the current-guiding junction, when forming metal circuits through electroplating, electroplating current can be evenly distributed over the circuit pattern section to form metal coating with uniform thickness, which enables upgraded production efficiency and reduced cost in manufacturing a 3D circuit device.
