CUSTOM LAYOUT OF INTEGRATED CIRCUIT (IC) DESIGNS

Systems and techniques for facilitating layout of an integrated circuit (IC) design are described. A distinct color pattern can be assigned to a set of shapes in a layout of the IC design that correspond to a net. Next, the layout of the IC design can be displayed in a graphical user interface (GUI) of the IC design tool. Some embodiments can move a diffusion region of a multigate device with respect to the location of the device contacts so that the diffusion region is aligned with respect to a set of fin tracks, wherein each fin of each multigate device is located on a fin track.
