Patent number: 10796067Abstract: Systems, methods, media, and other such embodiments described herein relate to critical area analysis (CAA) operations as part of electronic design automation (EDA). One embodiment involves accessing a circuit design having a first layer (which may be a composite layer), sampling the first layer, and performing an initial CAA using the sampled portions of the layer with a set of predetermined defect sizes. The initial CAA is used to automatically generate a model which can be used to accurately select input parameters (e.g., selected defect sizes) for a full analysis. A CAA characteristic is then calculated for the first layer using the input parameters. In various embodiments, different sampling percentages and criteria for selecting input parameters can be used to reduce the computing resources to compute a CAA characteristic, such as theta-bar, while limiting error to a threshold amount (e.g. less than one percent).Type: GrantFiled: April 19, 2019Date of Patent: October 6, 2020Assignee: Cadence Design Systems, Inc.Inventors: Jonathan R. Fales, Frank E. Gennari, Jeffrey E. Nelson, Jeffrey Russell, Ya-Chieh Lai, Jac Paul Condella

Patent number: 8832621Abstract: A system and method for evaluating a design layout by identifying squish patterns for configurations of shapes in windows defined for anchors in the layout, identifying deltas between edges of elements in the windows and reducing each delta to a single width are described. Identified squish patterns may be compared to known patterns to determine if the squish pattern is a known good or bad pattern. A squish pattern may be represented by a pixel map such that each pixel is a reduced delta in the window and each pixel has a bit representing a layer in a multi-layer layout. A plurality of stored squish patterns may be searched to identify a matching squish pattern, a specific configuration of the squish pattern, or configurations of the squish pattern having deltas within a specified range.Type: GrantFiled: November 28, 2011Date of Patent: September 9, 2014Assignee: Cadence Design Systems, Inc.Inventors: Frank E.

Patent number: 8769474Abstract: Disclosed are methods, systems, and articles of manufacture for using pattern matching with an integrated circuit layout including recognizing shapes within the IC layout, identifying features for the shapes, and extracting situations for the respective features. The method may further include simulating the situations to determine a set of situations for modification based on an OPC requirement, modifying the set of situations to improve satisfaction of the OPC requirement, and reintegrating the modified set of situations into the IC layout. The method may also include simulating a subset of the extracted situations to determine aerial images of the subset, and tiling the subset of situations to form a larger aerial image. The method may also include removing overlap from a window based on the situations extracted for the window, calculating a density for each of the situations, and calculating a density for the window based on the density.Type: GrantFiled: October 18, 2010Date of Patent: July 1, 2014Assignee: Cadence Design Systems, Inc.Inventors: Frank E.

Patent number: 8631373Abstract: Systems, methodologies and technologies for the analysis and transformation of integrated circuit layouts using situations are disclosed. A method for transforming an integrated circuit (IC) layout includes recognizing shapes within the IC layout, identifying features for each of the shapes and extracting situations for the respective features. Extracted situations can be used to improve optical proximity correction (OPC) of the IC layout. This improved OPC includes extracting the situations, simulating the situations to determine a set of the situations identified for modification based on failing to satisfy a desired OPC tolerance level, modifying the set of situations to improve satisfaction of the desired OPC tolerance level, and reintegrating the modified set of situations into the IC layout. Extracted situations can also be used to improve aerial image simulation of the IC layout.Type: GrantFiled: December 22, 2009Date of Patent: January 14, 2014Assignee: Cadence Design Systems, Inc.Inventors: Frank E.

Patent number: 8365103Abstract: Systems and methods for creating and implementing two-dimensional (2D), image-based design rules (IBDRs) are disclosed. Techniques for creating 2D IBDR can include identifying a search pattern that is representative of a 2D pattern of interest of a design, creating a pattern representation based on the search pattern, defining an anchor point for the pattern representation, and assigning weights to elements of the pattern representation. The 2D MDR can be used in systems and method for searching a design by comparing the 2D IBDR to the design. A number of 2D IBDRs can be merged into a subset of similar 2D IBDRs by characterizing desired rule geometries, sorting the 2D IBDRs into groups according to the desired rule geometries, merging the groups of 2D IBDRs into a single representative search pattern. Additionally, standard design rules can be created from the disclosed 2D IBDRs.Type: GrantFiled: December 22, 2009Date of Patent: January 29, 2013Assignee: Cadence Design Systems, Inc.Inventors: Frank E.

Patent number: 8079005Abstract: Disclosed is an approach for performing pattern classification for electronic designs. One advantage of this approach is that it can use fast pattern matching techniques to classify both patterns and markers based on geometric similarity. In this way, the large number of markers and hotspots that typically are identified within an electronic design can be subsumed and compressed into a much smaller set of pattern families. This significantly reduced the number of patterns that must be individually analyzed, which considerably reduces the quantity of system resources and time needed to analyze and verify a circuit design.Type: GrantFiled: September 30, 2008Date of Patent: December 13, 2011Assignee: Cadence Design Systems, Inc.Inventors: Ya-Chieh Lai, Frank E.
