    Type: Grant
    Filed: January 5, 2007
    Date of Patent: July 6, 2010
    Assignee: International Business Machines Corporation

  • Patent number: 7752580
    Abstract: Disclosed herein are embodiments of a system and an associated method for analyzing an integrated circuit to determine the value of a particular attribute (i.e., a physical or electrical property) in that integrated circuit. In the embodiments, an open deterministic sequencing technique is used to select a sequence of points representing centers of sample windows in an integrated circuit layout. Then, the value of the particular attribute is determined for each sample window and the results are accumulated in order to infer an overall value for that particular attribute for the entire integrated circuit layout. This sequencing technique has the advantage of allowing additional sample windows to be added and/or the sizes and shapes of the windows to be varied without hindering the quality of the sample.

  • Patent number: 7634745
    Abstract: In embodiments of a method critical area is calculated based on both independent and dependent compound fault mechanisms. Specifically, critical area is calculated by generating, for each simple fault mechanism in the compound fault mechanism, a map made up of polygonal regions, where values on a third dimensional z-axis represent the critical defect size for each single fault mechanism at a point x,y. These maps are overlaid and the planar faces (i.e., top surfaces) of each region of each map are projected onto the x,y plane in order to identify intersecting sub-regions. The dominant fault mechanism within each sub-region is identified based on an answer to predetermined Boolean expression and the critical areas for all of the sub-regions are accumulated in order to obtain the total critical area for the compound fault mechanism.

  • Patent number: 7503021
    Abstract: The invention provides a method, system, and program product for diagnosing an integrated circuit. In particular, the invention captures one or more images for each relevant circuit layer of the integrated circuit. Based on the image(s), a component netlist is generated. Further, a logic netlist is generated by applying hierarchical composition rules to the component netlist. The component netlist and/or logic netlist can be compared to a reference netlist to diagnose the integrated circuit. The invention can further generate a schematic based on the component netlist or logic netlist in which components are arranged according to port, power, and/or component pin connection information determined from the netlist. Further, the schematic can be displayed in a manner that wiring connections are selectively displayed to assist a user in intelligently arranging the circuit components.
