Abstract:
Aiming at the situation that current testability analysis methods are based on failure analysis, a quantitative testability analysis method based on system structure, performance and function is proposed. Mathematical definitions of this method are established, including the test set of system design characteristics, the direct relationship set among system function sets, performance sets, structure sets and test sets. Performance coverage rate, function coverage rate, and unit coverage rate are also defined. The engineering operation flow of this method is established, which includes establishing basic information, generating direct relationship between the information, calculating of test coverage rate, analyzing the design characteristics of terms which are not tested. A plane’s servo system is taken as an example for the engineering application, which shows that this method is feasible and effective.
