  • Patent number: 8762912
    Abstract: Some embodiments provide a system that facilitates the creation of a layout from a schematic in an electronic design automation (EDA) application. During operation, the system performs a tiered comparison of the schematic and the layout. The tiered comparison includes a first tier that compares labels in the schematic and the layout. The tiered comparison also includes a second tier that compares first-level connectivity in the schematic and the layout. The tiered comparison further includes a third tier that determines a graph isomorphism between the schematic and the layout. After the tiered comparison is completed, the system provides a result of the tiered comparison to a user of the EDA application. Finally, the system enables repairs of mismatches in the result by the user through a graphical user interface (GUI) associated with the EDA application.

Processes for creating and validating the constraints are provided by user-defined plug-ins, thereby allowing users to annotate circuit designs with constraints for proprietary layout and fabrication processes without exposing the constraints to tool vendors or competitors. The constraints are re-created from the template types whenever the circuit design is loaded into the EDA tool, so that the constraints are based upon the latest version of the template type. The constraints are also re-created when validation fails. Constraint groups are reusable in different designs, technology nodes, and processes because they automatically expand to provide the specific constraints to achieve a goal.

    Abstract: A method enables a user to create, edit, monitor and/or optimize the overall machine process of a programmable machine or system assisted by a graphics editor. The programmable machine or system is initially put together as a system of individual machine units which are involved in the overall machine process during certain times by running a number of partial machine processes that are firstly synchronized with one another once they have been set up and then parameters are set for them. These method steps take place in a two-dimensional process diagram created by the graphics editor that plots all the partial machine processes involved in the overall machine process via assigned process symbols that are positioned or repositioned by the graphics editor so that they are arranged in a machine component dimension and in a time dimension.

  • Patent number: 8683411
    Abstract: A global placer receives a plurality of regions, each region occupying a sub-area of a design area. receives a plurality of movebound objects, each movebound object associated with a region. The global placer receives a plurality of unconstrained objects, each unconstrained object associated with no region. The global placer receives a tolerance, wherein the placement tolerance defines a coronal fringe to at least one region. The global placer initially placing the plurality of movebound objects and unconstrained objects. The global placer iterates over objects without preference to region-affiliation to select an object, wherein the objects are comprised of the plurality of movebound objects and plurality of unconstrained objects. The global placer determines whether movebound object is within the tolerance of a region associated with the movebound object.

  • Patent number: 8677307
    Abstract: Disclosed are improved methods, systems, and computer program products for visualizing and estimating IC die arrangement for an electronic design, and for performing chip planning and estimation based upon the estimated and visualized IC die arrangements. According to some approaches, an interface is provided for visualizing different die arrangement options for an electronic design, in which a filmstrip view is provided to display smaller images of different die arrangement options, and a central viewing area is provided to view a larger image of a selected candidate die arrangement. The different images, whether smaller or larger images, are maintained with design object information and not just static images. This allows for selection and highlighting of individual objects within the die arrangement images, as well as corresponding highlighting of that same object in other images.

    Abstract: Methods and systems for viewing and debugging HDL designs having SystemVerilog interface constructs are provided. An HDL design code is received, wherein the design code comprises a first module, a second module and a SystemVerilog interface construct. A first object corresponding to the first module, a second object corresponding to the second module and an interface object corresponding to the interface construct are displayed in a schematic view. The interface object is disposed between the first and second objects, and a shape of the interface object is different from that of the first and second objects. The interface signals from the first object to the second object and the interface signals from the second object to the first object pass through the interface object.

  • Patent number: 8669537
    Abstract: A charged particle beam writing apparatus and a charged particle beam writing method capable of shortening the time necessary to generate shot data and improving writing throughput. A graphic pattern defined in write data is divided into graphics represented in shot units. The divided graphics are temporarily stored in a memory and are distributed to their corresponding subfield areas while developing position information defined in a state of being compressed to write data. When each pattern is written by multi-pass writing, graphics divided at a first pass are used for distribution to subfield areas after a second pass.
