  • Patent number: 12387026
    Abstract: A method for automatic control of a simulation error in an analog circuit and a use thereof are provided. The method first determines a measurement object and acquires a simulation standard by simulating the measurement object. Then, the method performs simulation based on different parameters of a circuit netlist to acquire an electrical parameter and/or circuit performance evaluation indicator of the measurement object during a simulation process. The method forms a simulation sampling dataset based on a simulation option combination parameter and an error corresponding to the simulation standard. Finally, the method optimizes and analyzes the simulation sampling dataset based on an artificial intelligence algorithm to acquire a simulation option combination that meets a simulation error requirement and takes a least time. The solution achieves automatic selection of the simulation option combination, improving the accuracy of the simulation result.

  • Patent number: 11499866
    Abstract: The invention relates to the technical field of mechanical vibration measurement, and discloses a device for accurately measuring mechanical vibration by photon counter. The device comprises a laser, an optical isolator, an adjustable attenuator, an optical fiber coupler, a single-photon counter and an FPGA post-processing module, wherein the laser enters the optical fiber coupler after passing through the optical isolator and the adjustable attenuator, and then enters into a measured object. The transmitted signal of the object to be measured returns to the optical fiber coupler and is output to the single-photon counter; the mechanical vibration of the measured object is analysed and obtained by the FPGA post-processing module connecting with the output terminal of the single-photon counter.
