Abstract: TPS (Test Program Sets) can be used in fault detection and maintenance of PCB. It is critical to the enhancement of maintainability of new equipment. Firstly the authors presented the main aspects of testability evaluation of TPS. Then，TPS testability evaluation methods based on fault injection were introduced. Finally，in the course of adequacy verification of test cover for the sample set of fault injection in physical simulation，the authors brought forward a testability modeling method based on multi-signal modeling methodology，which can achieve higher accuracy and efficiency.
Key words: TPS；Fault injection；Sample set；Evaluation；Verification
