Abstract
A routing process applied to design integrated circuits uses keep-through regions. Keep-through regions specify areas which metal shapes may overlap but where metal shapes may not have line ends. The keep-through regions are generated based on end-of-line rules applicable to routing of the design. These keep-through regions are then used in determining the layout of interconnects for the design. The interconnects are composed of metal shapes, and the line ends of the metal shapes are located in accordance with the keep-through regions
