V. THE REALIZATION OF TESTING PLATFORM A few key problems is needed to solve in order to realize the rapid test platform of redundant flight control computer software˖1) How to simulate multi-channel communication? The communication is the foundation of the synchronization simulation and cross-transmission˗2) How to simulate the multi-channel fault logic circuit? The multi-channel fault logic is the key feature of real redundant computer˗3) How to realize the underlying redundant function simulation API via encapsulating the real hardware driving API? 4) How to realize the function of fault injection?
