Abstract: A computer program product for generating test patterns for a pattern sensitive algorithm. The program product includes code for extracting feature samples from a layout design; grouping feature samples into clusters; selecting at least one area from the layout design that covers a feature sample from each cluster; and saving each pattern layout covered by the at least one area as test patterns.

Abstract: A method, system and program product to model an IC design to include dimensions such as a local width and spacing of IC shapes in a consistent fashion. In particular, the invention uses a core portion of Voronoi diagrams to partition edges of a shape into intervals and assigns at least one dimension to each interval such as a local width and spacing. Dimension assignment can be made as any desirable definition set for width and spacing, e.g., numerical values or continuous dimension-dependent design rules. Design rule checking for dimension-dependent spacing rules given in any arbitrary functional form of width and spacing is possible. Application of the invention can be made anywhere the width and spacing of VLSI shapes play a role, e.g., relative to a single edge, neighboring edges, neighboring shapes, and/or for edges in more than one layer of the IC design.

Abstract: Embodiments herein provide a method and computer program product for optimizing router settings to increase IC yield. A method begins by reviewing yield data in an IC manufacturing line to identify structure-specific mechanisms that impact IC yield. Next, the method establishes a structural identifier for each structure-specific mechanism, wherein the structural identifiers include wire codes, tags, and/or unique identifiers. Different structural identifiers are established for wires having different widths. Furthermore, the method establishes a weighting factor for each structure-specific mechanism, wherein higher weighting factors are established for structure-specific mechanisms comprising thick wires proximate to multiple thick wires. The method establishes the structural identifiers and the weighting factors for incidence of spacing between single wide lines, double wide lines, and triple wide lines and for incidence of wires above large metal lands.

Abstract: Disclosed is a method of locating systematic defects in integrated circuits. The invention first performs a preliminary extracting and index processing of the circuit design and then performs feature searching. When performing the preliminary extracting and index processing the invention establishes a window grid for the circuit design and merges basis patterns with shapes in the circuit design within each window of the window grid. The invention transforms shapes in a each window into feature vectors by finding intersections between the basis patterns and the shapes in the windows. Then, the invention clusters the feature vectors to produce an index of feature vectors. After performing the extracting and index processing, the invention performs the process of feature searching by first identifying a defect region window of the circuit layout and similarly merging basis patterns with shapes in the defect region window. This merging process can include rotating and mirroring the shapes in the defect region.
