Based on the problem of fast diagnosis and maintenance of mixed-signal system, the DFT and evaluation of the data collector which is the typical mixed-signal system are researched in this paper. Firstly, two types of advanced DFT technologies:the boundary-scan technology and the BIST technology are introduced. Then, the important capabilities of the data collector are illustrated. The fault types and the design scheme of the test modules in the system are presented. By computing and simulating in TEAMS, the testability design target based on the multi-signal flow model is analyzed. Finally, the results indicate that the DFT could improve the fault-test rate (FIR) and the fault-isolation rate (FIR ), increase the test cost and decrease the system reliability at the same time.
