    摘要: A method of layout optimization containing parameterized cells includes reading a physical design containing parameterized cells, creating a new version for each of usage of a given parameterized cell. The method optimizes physical design shapes of each new version of the parameterized cell by assigning variables to parameters of the parameterized cell according to a desired objective. Then, the method updates the parameters of each new version of the parameterized cell and replaces each new version of the parameterized cell with an instance of the parameterized cell having updated parameters. The method can optionally adjust physical design shapes based on constraints related to the parameters.

    摘要: A method, system and program product for context aware sub-circuit layout modification are disclosed. The method may include defining at least one context for the sub-circuit for each circuit that uses the sub-circuit; in the case that a plurality of contexts are defined, minimizing a number of contexts for the sub-circuit by combining contexts into at least one stage; placing each stage into a staged layout; and modifying the sub-circuit by modifying the staged layout.

    摘要: A method of polygonal area design rule correction for use in an electronic design automation tool for governing integrated circuit (IC) design layouts using one-dimensional (1-D) optimization, with steps of analyzing IC design layout data to identify violating polygons, partitioning violating polygons into rectangles in a direction of optimization, formulating an area constraint for each violating polygon to formulate a global linear programming (LP) problem that includes each constraint for each violating polygon and solving the global LP problem to obtain a real-valued solution. A next LP problem is created for each area constraint, and solved. The creating a next and solving the next LP problem and solving are repeated until the last “next LP problem” is solved using constraints and objectives representing sums or differences of no more than two optimization variables.

    摘要: Methods, systems and program products are disclosed for selectively scaling an integrated circuit (IC) design: by layer, by unit, or by ground rule, or a combination of these. The selective scaling technique can be applied in a feedback loop with the manufacturing system with process and yield feedback, during the life of a design, to increase yield in early processes in such a way that hierarchy is preserved. The invention removes the need to involve designers in improving yield where new technologies such as maskless fabrication are implemented.
