Abstract
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.

A method for facilitating custom layout of an IC design, the method comprising:
- for each net in a set of nets in the IC design, assigning a distinct color pattern to a set of shapes in a layout of the IC design that correspond to the net, wherein each shape in the set of shapes corresponds to a physical structure in an IC chip that can be manufactured based on the IC design;
- and
- displaying the layout of the IC design in a graphical user interface (GUI) of the IC design tool, wherein each shape in the layout of the IC design is displayed in the GUI of the IC design tool using the color pattern assigned to the shape.
A non-transitory computer-readable storage medium storing instructions that, when executed by a computer, cause the computer to perform a method for facilitating custom layout of an integrated circuit (IC) design, the method comprising:
- for each net in a set of nets in the IC design, assigning a distinct color pattern to a set of shapes in a layout of the IC design that correspond to the net, wherein each shape in the set of shapes corresponds to a physical structure in an IC chip that can be manufactured based on the IC design;
- and
- displaying the layout of the IC design in a graphical user interface (GUI) of the IC design tool, wherein each shape in the layout of the IC design is displayed in the GUI of the IC design tool using the color pattern assigned to the shape.
A method for facilitating custom layout of multigate devices, the method comprising:
- placing a multigate device in an IC design layout so that a device contact of the multigate device is aligned with respect to a set of interconnection tracks, wherein electrical connections between circuit elements in the IC design layout are routed along interconnection tracks;
- and
- moving a diffusion region of the multigate device with respect to the location of the device contact 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.
