Design of automatic line fault injection equipment and verification of BIT detection capability

To verify the BIT detection capabilities of electronic products, an automatic line fault injection equipment is designed. This paper shows the overall function and the overall structure of the equipment. Based on the function and the overall structure, the communication protocol between the computer and the fault injection equipment is designed. The BIT detection capability verification process based on the equipment is also given. Finally, a case of fault injection experiments to an environmental control system is given, and the result shows that the equipment is available and effective.
