Abstract
A system and method for optimizing a design layout by identifying features for abutment where shapes of the features that trigger the abutment are overlapping or within a predefined proximity of each other. The abutment process is implemented for features that have overlapping pins or that will have overlapping pins when abutted. Connectivity of abutted features is analyzed for the overlapped pins; pins of one of the abutted features are swapped so that at least one overlapping set of horizontal pins is connected to a same net; and a pin of the abutted features can be shortened as necessary to prevent short-circuit between pins connected to different nets. The overlapping pins are then merged. Pins can be shortened by cutting the pin or by adjusting pin style or pin size.
