  • Patent number: 8375347
    Abstract: A method of designing an integrated circuit (“IC”) is provided that includes placing an IC design, where the IC design includes a first element, a second element, and a path coupling the first and second elements, and routing the IC design. Further, the method includes obtaining at least one of resistivity data and capacitance data related to the path, and obtaining timing data related to the path. The method also includes using at least one of the resistivity data, the capacitance data, and the timing data to determine a critical dimension (“CD”) bias to be applied to the path, and modifying the IC design, where modifying includes applying the CD bias to the path.

  • Patent number: 8365115
    Abstract: A system and method for performance modeling of integrated circuits is provided. A method for performing timing analysis on an integrated circuit is provided, the integrated circuit having a timing path. The method includes computing a number of non-common timing path elements in the timing path, assigning a timing de-rate factor to the timing path based on the number of non-common timing path elements, and computing a timing analysis on the integrated circuit using the assigned timing de-rate factor.

  • Patent number: 8286119
    Abstract: A method for integrated circuit design includes providing a layout of an integrated circuit; determining key parameters of the integrated circuit; determining target values of the key parameters; and performing a first shrinkage of the layout using a first shrink percentage to generate a shrunk layout. The shrunk layout is evaluated by generating values of the key parameters from the shrunk layout. A portion of the values of the key parameters failing to meet respective ones of the target values is found. Guidelines for tuning manufacturing processes of the shrunk layout are provided, so that the portion of the values of the key parameters can meet the respective ones of the target values.
