  • Patent number: 9449140
    Abstract: Among other things, one or more techniques and systems for performing design layout are provided. An initial design layout is associated with an electrical component, such as a standard cell. A conflict graph is generated based upon the initial design layout. The conflict graph comprises one or more nodes, representing polygons within the initial design layout, connected by one or more edges. A same-process edge specifies that two nodes are to be generated by the same pattern process, while a different-process edge specified that two nodes are to be generated by different pattern processes, such as a mandrel pattern process and a passive fill pattern process. The conflict graph is evaluated to identify a conflict, such as a self-aligned multiple pattering (SAMP) conflict, associated with the initial design layout. The conflict is visually displayed so that the initial design layout can be modified to resolve the conflict.
