Patents by Inventor Wai-Yan Ho

Wai-Yan Ho has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11847397
    Abstract: Any primitive cells or blocks can be represented physically by a Barycenter compact model (or Barycenter model), and any black box model can also be physically represented by a Barycenter compact model physically. A boundary condition between blocks is formulated by the Barycenter compact model. Boundary condition problems between blocks can be limited within two levels only if using the Barycenter compact model.
    Type: Grant

  • Patent number: 10558772
    Abstract: A circuit is simulated by using system or network tearing to obtain a real solution. The circuit may be an entire integrated circuit, portion of an integrated circuit, or a circuit block. A circuit simulation technique of the invention generates a system graph, finds a tree, and partitions the tree into two or more subtrees. The technique identifies global links and local links in the graph. Each subtree may be solved individually using distributed, parallel computing. Using the results for the subtrees, the technique obtains a real solution, branch voltages and currents, for the circuit.

  • Patent number: 10068043
    Abstract: A technique validates results from a circuit simulation estimation program. The technique determines whether the estimated results satisfy Kirchhoff's current law (KCL), Kirchhoff's voltage laws (KVL), and power conservation for the original circuit. A reporting tool shows the validation results and may be customized by the user. The tool can show in the original circuitry where the estimated results may be inaccurate.

  • Patent number: 9984195
    Abstract: A system or technique provides for a hierarchical visual-based analysis of electrical integrated circuit system simulation results. A three-dimensional or 3D visualization may be used to identify and conduct an analysis of the integrated circuit. An analysis is done on a specific feature of the integrated circuit that is visible in the three-dimensional visualization. The specific feature may be one that is obscured by other layers of the integrated circuit visualization.
