    Abstract: Systems and methods for context aware circuit design are described herein. A method includes: identifying at least one cell to be designed into a circuit; identifying at least one context parameter having an impact to layout dependent effect of the circuit; generating, for each cell and for each context parameter, a plurality of abutment environments associated with the cell; estimating, for each cell and each context parameter, a sensitivity of at least one electrical property of the cell to the context parameter by generating a plurality of electrical property values of the cell under the plurality of abutment environments; and determining whether each context parameter is a key context parameter for a static analysis of the circuit, based on the sensitivity of the at least one electrical property of each cell and based on at least one predetermined threshold.

    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 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.
