  • Patent number: 11188705
    Abstract: An efficient electronic structure for circuit design, testing and/or manufacture for validating a cell layout design using an intelligent engine trained using selectively arranged cells selected from a cell library. An initial design rule violation (DRV) prediction engine is initially trained using a plurality of pin patterns generated by predefined cell placement combinations, where pin patterns are pixelized and quantified and is classified as either (i) a DRV pin pattern (i.e., pin patterns likely to produce a DRV) or (ii) a DRV-clean pin pattern (i.e., pin patterns unlikely to produce a DRV).
    Type: Grant
    Filed: May 15, 2020
    Date of Patent: November 30, 2021
    Assignee: Synopsys, Inc.

  • Patent number: 8875083
    Abstract: Disclosed herein are rouging methods and devices for a flip-chip package. The flip chip includes several outer pads and several inner pads. The routing method includes: setting an outer sequence based on the arrangement order of the outer pads; setting several inner sequences based on the connection relationships between inner pads and the outer pads; calculating the longest common subsequence of each inner sequence and the outer sequence, defining the connection relationships between the inner pads and the outer pads corresponding to the longest common subsequence as direct connections, and defining the connection relationships between the inner pads and the outer pads that do not correspond to the longest common subsequence as detour connections; establishing the routing scheme of the flip chip based on the connection relationships between the inner pads and the outer pads.
