Abstract:
1. A method for assessing fit of a pattern of features with a second pattern of features, including the steps of: processing data indicative of the pattern to generate data indicative of a feature-relating tolerance consumed circle having a center; generating a float remaining circle having a diameter and a center position by processing data indicative of the pattern, wherein the diameter is indicative of float remaining in the pattern, and the center position of the float remaining circle is determined by the center of the feature-relating tolerance consumed circle; generating a second float remaining circle, having a diameter indicative of float remaining in the second pattern, by processing data indicative of the second pattern, determining a common framework for the features of the pattern and the features of the second pattern, such that the common framework determines relative location of the float remaining circle and the second float remaining circle; generating an adjusted float remaining circle by processing data indicative of an adjusted version of the pattern; and using the float remaining circle and the second float remaining circle to assess fit of the pattern with the second pattern, and using the adjusted float remaining circle and the second float remaining circle to assess fit of the adjusted version of the pattern with the second pattern.
