  • Pattern based die connector assignment using machine learning image recognition
    Patent number: 11620427
    Abstract: A method for assigning connections between IO pad pins and connectors on an integrated circuit (IC) die. A pattern (300) including a physical layout of connectors (302) and pad pins (304) is associated with a mapping of connections between the connectors (302) and the pad pins (304). A processor (204) identifies instances (402, 404) of the pattern (300) within a design image (400) of an integrated circuit (IC) die using a machine learning model. The design image (400) includes a physical layout of connectors (414) and pad pins (416). For each identified instance (402, 404) of the pattern (300) within the design image (400), the mapping of connections is assigned to respective connectors (414) and pad pins (416) in the identified instance (402, 404).
