Patents by Inventor Tamal Basu

Tamal Basu 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: 7539966
    Abstract: Enhanced algorithms are provided for finding circuit edit locations which utilize automated conversions from circuit schematic to physical layout design. The enhanced algorithms further include a user interface enabling the user to provide preferences, limitations, and constraints in order to bias the search to be conducted, as well as using the provided design data in order to locate the best positions for particular edit schemes, including net cuts and net joins.
    Type: Grant
    Filed: August 11, 2006
    Date of Patent: May 26, 2009
    Assignee: DCG Systems, Inc.
    Inventors: Tamal Basu, Saurabh Gupta, Tahir Malik, Hitesh Suri
  • Patent number: 7530034
    Abstract: A method and apparatus for defining a circuit operation, such as a charged particle beam operation to perform a circuit edit and define a probe point. Circuit operation definition is performed in a front-end environment with access to integrated circuit computer aided design tools providing logic level and layout level information concerning the integrated circuit. The front-end environment incorporates circuit operation optimization methods to identify optimal locations for a circuit operation. A back-end environment, such as a charged particle tool computing platform, is adapted to receive one or more files, which may include a truncated layout file with circuit operation location information, for use in further defining a circuit operation and/or performing the circuit operation.
