Abstract: Design for testability (DFT) is an important approach to improve the manufacturing efficiency and test quality of a system. The hierarchical structure of DFT for AOCS of spacecraft based on 1553B bus architecture is given and the model frame of DFT is built. The technical realization of DFT is also analyzed. The software TEAMS(testability engineering and maintenance system) is used to simulate and evaluate the DFT via an example and the simulation result demonstrates the validity of this method.

Key words: DFT, testability standards, busbased configuration, control system of spacecraft
