    Abstract: A method of optimizing hierarchical very large scale integration (VLSI) design by use of cluster-based cell cloning. The method of the present invention provides improved yield or migration by reusing cells in order to reduce the number of unique instances of at least one of the reused cells. The method performs hierarchal optimization on the reduced set of clones (i.e., clusters). The method of the present disclosure includes, but is not limited to, the steps of setting the initial clustering parameters; assembling the physical design from existing reused cells; for each cell type, performing a full cloning operation in order to create a full set of duplicate cells; for each cell type, performing a full optimization of the design; for each cell type, performing an analyses of all cell environments and performing a clustering operation; and analyzing the overall results in order to determine whether the optimization objectives are achieved.

    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. Subsequently, the router settings are modified based on the structural identifiers and the weighting factors to minimize systematic defects.

    Abstract: Disclosed is a method that predicts test yield for a semiconductor product, prior to design layout. This is accomplished by applying a critical area analysis to individual library elements that are used to form a specific product and by estimating the test yield impact of combining these library elements. For example, the method considers the test yield impact of sensitivity to library element to library element shorts and the test yield impact of sensitivity to wiring faults. The disclosed method further allows die size growth to be traded off against the use of library elements with higher test yield in order to provide an optimal design solution. Thus, the method may be used to modify library element selection so as to optimize test yield. Lastly, the method further repeats itself at key design checkpoints to revalidate initial test yield (and cost) assumptions made when the product was quoted to a customer. Thus, the method provides increased accuracy of test yield estimate from initial sizing through design and further allows designs to be modified to improve test yield.
