In this paper, based on the functional role model theory, the reasoning rule and the technique of FMEA, which are facing to BuiltinTest (BIT), are developed.
The built-intest (BIT) design of hardware and software is also introduced in this dissertation. The BIT design consists of analog inputs, digital inputs and digital outputs.
The techniques used to improve the reliability of the controller are explained in detail, and the formation and realization of BIT (BuiltInTest) system are presented.
