Testability modeling could improve the capability of spacecraft’s autonomous detection, and reduce design risks efficiently so as to master its running state precisely. This paper demonstrates the principle of testability modeling, and testability modeling design and analysis flow is put forward, and then take some spacecraft typical system as an example to design and applicate through multi-signal graphical modeling method. The experimental result shows that this design method works well, and the technology indicators meets design needs.
