  • Patent number: 11886788
    Abstract: A computing system may include a circuit design access engine configured to access a circuit design. The computing system may also include a duplicate section processing engine configured to partition the circuit design into multiple circuit sections and determine, from among the multiple circuit sections, an identical section set based on duplicate criteria. Circuit sections of the identical section set may satisfy the duplicate criteria with respect to one another. The duplicate section processing engine may further be configured to perform an OPC processing operation on a selected circuit section of the identical section set and apply an OPC result of the performed OPC processing operation for other circuit sections of the identical section set instead of or without performing the OPC processing operation on the other circuit sections of the identical section set.

  • Patent number: 11113445
    Abstract: Aspects of the disclosed technology relate to techniques of hotspot detection. Pinching-type hotspot candidates and bridging-type hotspot candidates are first identified in the layout design based on predetermined criteria. Simulation is then performed to derive aerial image intensity values for a plurality of sites on each of the pinching-type and bridging-type hotspot candidates. Pinching-type hotspots are determined from the pinching-type hotspot candidates based on one or more machine learning models for pinching-type hotspots, and bridging-type hotspots are determined from the bridging-type hotspot candidates based on one or more machine learning models for bridging-type hotspots. The input vector for the machine learning models is the aerial image intensity values for the plurality of sites.

  • Patent number: 11003828
    Abstract: Systems and methods for layout analysis using unit cell properties. A method includes receiving a layout design and analyzing the layout design to identify unit cells in the layout design. The method includes designating points of interest each corresponding to a respective one of the unit cells and classifying the unit cells into a plurality of classifications using the points of interest and the corresponding properties. The method includes identifying unique patterns of the unit cells, and producing a reduced layout including the unique patterns of unit cells. The method includes performing layout processing on the reduced layout and propagating the process results from each of the unique patterns of unit cells in the reduced layout to other unit cells of the layout design having the same classification.

  • Patent number: 10311199
    Abstract: Aspects of the disclosed technology relate to techniques of pattern matching. Matching rectangles in a layout design that match rectangle members of a search pattern are identified based on edge operations. The rectangle members comprise an origin rectangle member and one or more reference rectangle members. Grid element identification values are attached to the matching rectangles. The matching rectangles that match the one or more reference rectangle members in neighborhoods of the matching rectangles that match the origin rectangle member are then analyzed. The neighborhoods are determined based on the grid element identification values. Based on the analysis, matching patterns in the layout design that match the search pattern are determined.

  • Patent number: 7802226
    Abstract: A method for preparing data to create two or more masks required to print a desired feature pattern with a multiple mask technique. In one embodiment of the invention, a target feature pattern is separated into two or more groups or data layers with a coloring algorithm. Coloring conflicts or adjacent features that are within a predetermined distance of each other and are assigned to the same group or data layer are identified. Cutting boxes are added to a feature to divide a feature into two or more smaller features. A coloring algorithm is re-applied to the layout including the cutting boxes to assign the features into different groups or data layers. Data in each group or data layer is used to define a mask to print the target feature pattern.
