| Abstract: |
| Automatic diagnostic information generation is one of the remarkable advantages of model checking methods. It is very important to understand the reason for the failure and fix the problem. In this paper, how to generate effective diagnosis in model checking value-passing processes is discussed. Two diagnostic forms, proof graph and witness, are defined. Moreover, algorithms are proposed to construct them from the search states space in model checking process. By this way, useful diagnoses are generated from the existing information by less calculation. Besides above, the algorithms have been implemented and used to analyze several cases. The experimental results show that this method is efficient. |
