Multi-phenomenon Oriented Embedded Software Fault Diagnosis

摘要

In order to locate the software fault more quickly and accurately, the positioning statement or software module involved in different test cases were sorted by the possibility of attributing to the software failure, which was calculated by using the method of correlation coefficient. Then, method of range analysis and variance analysis were introduced to address the issue of the volatility in some condition, which can also be extended to solve the problem of different fault phenomenon with different importance factor. Finally an example of the method was given to verify its effectiveness.
