    Abstract: A method comprises providing a non-transitory, machine-readable storage medium storing a partial netlist of at least a portion of a previously taped-out integrated circuit (IC) layout, representing a set of photomasks for fabricating an IC having the IC layout such that the IC meets a first specification value. A computer identities a proper subset of a plurality of first devices in the IC layout, such that replacement of the proper subset of the first devices by second devices in a revised IC layout satisfies a second specification value different from the first specification value. At least one layout mask is generated and stored in at least one non-transitory machine readable storage medium, accessible by a tool for forming at least one additional photomask, such that the set of photomasks and the at least one additional photomask are usable to fabricate an IC according to the revised IC layout.

    Abstract: A switch cell structure includes a switch cell of a first type, which includes a master switch cell and a plurality of slave switch cells. The master switch cell includes a buffer having an input and an output and a transistor having a gate coupled to the output of the buffer. The slave switch cell includes a respective signal line having an input and output and a transistor having a gate coupled to the signal line, the signal lines of the slave switch cells are coupled to one another, with the output of one coupled to the input of another of the signal lines. The output of the buffer of the master switch cell is coupled to an input of one of the signal lines of slave switch cells to drive the plurality of slave switch cells.

    Abstract: Some embodiments of the present disclosure relates to a method and apparatus to achieve a layout that is compatible with a multiple-patterning process. Two or more unit cells are constructed with layouts which satisfy the properties of the multiple-patterning process, and are each decomposed into two or more colors to support the multiple-patterning process. An active layout feature is merged with a dummy wire at a shared boundary between two unit cells. In the event of a short between two active layout features at the shared boundary, an automatic post-layout method can rearrange the layout features in a vicinity of the shared boundary to separate the active layout features to achieve cell functionality while satisfying the multiple-patterning properties.
