| Abstract: | Aimed at the difficulties in associated debugging and long testing period and complex conditions in the simulation and testing of the redundant computer software,a kind of method based on single PC is proposed.According to the conception of finite-state machine,the redundant flight control system software is scheduled.Besides,the notion of virtual timestamp is employed to simulate the communication process between channels.It is supposed to test the function of the software at the beginning of design.Moreover,in term of the conception of virtual timestamp,the fault and exception handles an be simulated conveniently. |
