A method for enabling jogging functionality in circuit designs utilizing DPT without the need for difficult to implement tools such as stitch-aware routing tools is disclosed. Embodiments include: displaying a user interface for generating an IC having a plurality of masks for a single layer; causing, at least in part, a presentation in the user interface of a cell placement of the IC that includes a filler cell; and designating a portion of the filler cell as a routing zone, the routing zone being configured such that routes placed in the routing zone are decomposable with other routes placed outside the filler cell.
