Classification: G06F

Abstract:
A rule-driven method for editing a physical integrated circuit layout comprised of a plurality of working shapes, comprising the machine executed steps of:creating a desired working shape that is shown on a computer monitor; calculating a width value associated with said desired working shape; verifying if the width value violates a minimum distance as defined by relevant design rules of an applied fabrication technology; and automatically adjusting geometry of said desired working shape to comply with the relevant design rules upon verification that the width value violates the minimum distance; wherein each of the working shapes is multi-edge, and the width value is the distance between a selected edge and an opposite facing edge of said desired working shape; wherein the step of automatically adjusting the geometry of said desired working shape includes the sub-step of rebounding the selected edge to a rebounding spot that is displaced by the minimum distance from the opposite facing edge; and further comprising the step of creating a ruler that is disposed between the selected edge and the opposite facing edge and that is shown on the computer monitor.
