Description

technical field [0001] The invention relates to the technical field of fault injection, in particular to a fault injection system and method for high-voltage digital signals. Background technique [0002] The fault injection of 110V digital signal can be applied to the debugging, testing and verification process of 110V digital acquisition equipment. By simulating the abnormality of the 110V digital signal, the response of the 110V digital acquisition equipment to the fault signal is tested, and the fault detection and fault handling capabilities of the 110V digital acquisition equipment are verified. [0003] At present, the fault injection for 110V digital signal is generally only the signal on-off, series impedance, parallel impedance and other fault injection of the physical layer. Due to the high voltage value, the fault injection of the electrical layer has not been realized. Contents of the invention [0004] In order to solve the above technical problems, embodime...
