Abstract
A system and method for optimizing a design layout by identifying features for abutment where the shapes that trigger the abutment are overlapping, within a predefined proximity of each other, or are interface elements for features having a short circuit. The abutment process may identify shapes for abutment that are not connected to a netlist of the design or are otherwise not associated with a connection pin. The abutment process may adjust a shape or feature including, for example by resizing, moving, inserting, or removing one or more shapes from the layout in accordance with predefined layout rules. After the shapes and features have been adjusted abutments may be formed between the features.
