  • Patent number: 11714948
    Abstract: The present disclosure relates to a system and method for use in an electronic circuit design. Embodiments may include receiving, using a processor, one or more DFM rules files from at least one PCB fabricator and importing the one or more DFM rules files to a DFM rule aggregator database. Embodiments may also include grouping one or more rules associated with the one or more DFM rules files using an automated or manual operation. Embodiments may further include performing automatic or manual rule aggregation on the grouped rules based upon, at least in part, rules aggregation information including a DFM template file.

  • Patent number: 11263381
    Abstract: Embodiments include herein are directed towards a method for use in an electronic design environment is provided. Embodiments may include receiving, using a processor, an electronic design and providing, at a graphical user interface, an option to change an object associated with the electronic design. Embodiments may further include identifying a damage area associated with the electronic design, the damage area including an object therein. Embodiments may also include generating a polygon for the damage area and caching one or more voids located outside of the damage area. Embodiments may further include performing a cut and stamp operation on a portion of the electronic design associated with the damage area and populating, at the graphical user interface, a repaired damage area.

  • Patent number: 10691868
    Abstract: The present disclosure relates to a system and method for use in an electronic circuit design. Embodiments may include an electronic computer aided design (“CAD”) system configured to receive one or more design rules and to receive one or more manufacturing rules. The CAD system may be further configured to analyze design database objects from the electronic design with respect to the manufacturing rules. The CAD system may generate a manufacturing output file, based upon, at least in part, the analyzing. Embodiments may also include a signoff computer aided manufacturing (“CAM”) station configured to receive the manufacturing output file. The CAM station may be configured to attempt to validate the manufacturing output file.

  • Patent number: 9990456
    Abstract: The present disclosure relates to a method for routing in an electronic circuit design. Embodiments may include receiving, at one or more computing devices, the electronic circuit design having a plurality of terminal pads associated therewith. Embodiments may further include generating a change in at least one of a size or an existence of at least one of the plurality of terminal pads. Embodiments may also include routing a portion of the electronic design based upon, at least in part, the generated change.

  • Patent number: 9202001
    Abstract: The present disclosure relates to a computer-implemented method for routing in an electronic circuit design. The method may include assigning a plurality of rats interconnecting one or more terminals associated with a layout of the electronic circuit design to a bundle. The method may further include sequencing the plurality of rats within the assigned bundle to generate a defined sequence of rats within the assigned bundle. The method may also include routing the plurality of rats between the one or more terminals, based upon, at least in part, the defined sequence.

  • Patent number: 8910105
    Abstract: The present disclosure relates to a method for routing in an electronic circuit design. The method may include assigning a plurality of rats interconnecting one or more terminals associated with a layout of the electronic circuit design to a bundle. The method may also include generating an independent breakout of the plurality of rats from a source end and a target end of the bundle. The method may further include sequencing the plurality of rats within the assigned bundle to generate a defined sequence of rats within the assigned bundle based upon, at least in part, the source end of the bundle. The method may additionally include generating a costed sequence breakout at the target end of the bundle, based upon, at least in part, a costed sequence analysis. The method may also include determining if the costed sequence breakout meets at least one criteria associated with the electronic design.

  • Patent number: 8726222
    Abstract: A system and method are provided for establishing an automated routing environment in an electronic design automation (EDA) work flow for the routing of a circuit design. A user may merely specify a flow via pattern, a flow via location, and a start and end terminal and thereby, the auto router or path finder will automatically find the least-cost paths between each of the start terminals through at least one intermediate via of the flow via and ending at an end terminal. Upon successful routing of all needed terminals, an at least partially routed circuit design may be output.

  • Patent number: 8479138
    Abstract: Techniques that can improve the efficiency of routing where connections are subject to elongation constraints. The design can be optimized by estimating elongation needed to meet constraints after an initial routing solution has been generated, but before elongation is actually applied to detailed paths. Paths can be re-routed at this earlier stage if it is determined that too much elongation, or too much elongation in crowded areas, will need to be added after the detail routing stage.
