[Abstract]:The increasing software and hardware system scale and system reliability requirements put forward higher requirements for software development and testing. Fault injection is an important testing method to measure the fault tolerance and anti-jamming ability of the system. The introduction of fault value or signal into the system can simulate the external disturbance and system disturbance in the real environment. The system fault-tolerant mechanism or recovery mechanism under abnormal state detection is achieved. Nowadays, the fault injection technology is becoming more and more mature, especially in the fault injection technology realized by software or simulation, there are still some problems, such as low injection precision, poor injection performance and long test period. With the help of the characteristic that the simulator is easy to control and track the program, this paper studies and optimizes the fault injection under the simulator environment, so as to realize the high performance fault injection under the high injection precision. To improve the efficiency of fault injection testing, shorten the test development cycle. The research work in this paper is as follows: 1) the characteristics of read-write behavior at fault injection point are studied, and the redundant injection phenomenon in fault injection process is found, and a command-level fault injection model is proposed for this phenomenon. And the minimum injection principle of optimization in the design phase of fault rules; 2) based on the instruction-level fault injection model, the runtime and static de-redundancy optimization injection methods in simulator environment are studied and implemented. The method of log recording based on shared memory is designed and implemented to solve the problem of log loss when the program crashes due to fault injection. 3) the fault injection execution acceleration technology based on instruction injection and compilation technology for software fault in simulator environment is studied and implemented. 4) the above functions are systematically tested to verify the effectiveness of the work in this paper.
