    摘要: A received layout identifies a plurality of circuit components to be included in an integrated circuit (IC) layer for double patterning the layer using two photomasks, the layout including a plurality of first patterns to be included in the first photomask and at least one second pattern to be included in the second photomask. A selected one of the first patterns has first and second endpoints, to be replaced by a replacement pattern connecting the first endpoint to a third endpoint. At least one respective keep-out region is provided adjacent to each respective remaining first pattern except for the selected first pattern. Data are generated representing the replacement pattern, such that no part of the replacement pattern is formed in any of the keep-out regions. Data representing the remaining first patterns and the replacement pattern are output.

    摘要: A method for dummy metal and dummy via insertion is provided. In one embodiment, dummy metals are inserted using a place and route tool, where the place and route tool has timing-awareness. Then, dummy vias arrays are inserted inside an overlap area of dummy metals using a design-rule-checking utility. Fine-grained dummy vias arrays are inserted in available space far away from main patterns. The dummy-patterns resulting from the inserted dummy vias are compressed using the design-rule-checking utility to reduce the size of a graphic data system file generated from the integrated circuit design. The dummy vias can be inserted with relaxed via spacing rules. The dummy metals are inserted with a constant line-end spacing between them for better process control and the maximum length of the dummy metal can be limited for smaller coupling effects. The dummy vias can have various sizes and a square or rectangular shape.

    摘要: Apparatus is provided for performing timing analysis on a circuit. A first storage device portion stores a state dependent stage weight for each of a rising time arc and a falling time arc of each of a plurality of cells in a cell library. An adder is provided for calculating a sum of the state dependent stage weights for each of the cells that are included in a circuit path. A second storage device portion stores a table containing on chip variation (OCV) derating factors. The table is indexed by values of the sum. A total path delay is calculated for the circuit path, based on the OCV derating factor corresponding to the sum of the state dependent stage weights for the cells in the circuit path.

    摘要: A method of designing a 3D integrated circuit (3D IC) including providing a first layout corresponding to a first device of a 3D IC and a second layout corresponding to a second device of a 3D IC is provided. A verification, such as LVS or DRC, may be performed not only on each device separately, but may also be performed to ensure proper connectivity between devices. The verification may be performed on a single layout file (e.g., GDS II file) including the interface layer of the first and second die. Dummy feature pattern may be determined for the 3D IC using a layout including the interface layers of the first and second devices.
