摘要
A memory is encoded with a data structure that represents a pattern having a range for one or more dimensions and/or positions of line segments therein. The data structure identifies two or more line segments that are located at a boundary of the pattern. The data structure also includes at least one set of values that identify a maximum limit and a minimum limit (i.e. the range) between which relative location and/or dimension of an additional line segment of the pattern in a portion of a layout of an integrated circuit (IC) chip, represents a defect in the IC chip when fabricated. In most embodiments, multiple ranges are specified in such a range defining pattern for example a width range is specified for the width of a trace of material in the layout and a spacing range is specified for the separation distance between two adjacent traces in the layout.
