Research on software fault mode time prediction method based on Matlab/Simulink virtual simulation

Reliability is a very important index of software, which needs strict testing, which is time-consuming and laborious. Traditional software reliability testing is carried out in the order of "constructing scenario profile, generating test cases and executing reliability testing". Only when the test samples are very rich, the test data generated by random sampling can accurately reflect the use distribution of the software. The increase of test data leads to the increase of profile, and the data collection is very difficult, so the existing test methods can not be widely tested. This paper analyzes the limitations of current software reliability testing, and puts forward a software failure mode time prediction method based on Matlab/Simulink virtual simulation, which can increase the description of software scene and monitor software reliability related data in real time. The test shows that the failure time can be obtained efficiently and quickly through the known failure mode, which can provide verification and data support for the research of software reliability.
