Abstract: A method for designing and verifying system engineering based on fishbone model is provided. System-level static information, system-task-level static information, and system-task-level dynamic data flow are acquired. Based on fishbone diagram, the system-level static information is represented as a system static composite structure diagram, and the system-task-level static information is represented as a system task composite structure diagram. Based on the fishbone diagram, the system-task-level dynamic data flow is represented as a system function point dynamic data flow diagram. Based on the system task composite structure diagram and the system function point dynamic data flow diagram, a static set and a dynamic set of software function modules of the system are established, and consistency adjustment is performed between the software function modules in the static set and the dynamic set. A designing and verifying system is further provided.

Abstract: Embodiments of the present disclosure provide a connector, an electronic device and an open pluggable specification (OPS) device. The connector includes a plurality of first pins and a plurality of second pins. A pair of adjacent first pins are configured to transmit a first signal. The plurality of the second pins are arranged on both sides of the pair of the first pins. The plurality of the second pins are configured to be grounded or transmit a second signal. A transmission rate of the first signal is greater than that of the second signal.
