Patents by Inventor Chi-Chong Lo

Chi-Chong Lo 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).

  • Method and apparatus for detecting and analyzing the propagation of noise through an integrated circuit
    Patent number: 7263676
    Abstract: One embodiment of the invention provides a system that analyzes the propagation of noise through an integrated circuit. During operation, the system obtains an input noise signal to be applied to a cell within the integrated circuit. The system then looks up parameters specifying how noise affects the cell, and then uses the parameters to determine how the input noise signal affects the cell. This can involve determining if the input noise signal will cause the cell to fail and/or determining a propagated noise signal that emanates from the cell.
    Type: Grant

  • Method and apparatus for characterizing the propagation of noise through a cell in an integrated circuit
    Patent number: 7007252
    Abstract: One embodiment of the invention provides a system that characterizes cells within an integrated circuit. During operation, the system obtains a number of input noise signals to be applied to the cell. The system then simulates responses of the cell to each of the input noise signals, and stores a representation of the responses. This allows a subsequent analysis operation to access the stored representation to determine a response of the cell instead of having to perform a time-consuming simulation operation.
