Multiple via connections using connectivity rings
Among other things, one or more techniques and/or systems for performing design layout are provided. In an example, a design layout corresponds to a layout of a standard cell whose connectivity is described by a netlist. For example, the netlist specifies net types for respective vias of the standard cell. One or more connectivity rings are formed within the design layout to provide connectivity for one or more vias of the design layout. For example, a first connectivity ring is generated, such as from mandrel, to connect one or more ring one vias. A second connectivity ring is generated, such as from passive pattern, to connect one or more ring two vias. One or more cuts are generated within the design layout to isolate vias having different net types. In this way, the design layout is self-aligned double patterning (SADP) compliant.
