Aiming at the difficulty of verification and test caused by the complex structure and timing logic of multi-source data fusion flight control software algorithm, this paper puts forward the digital simulation technology of flight control software, which simulates the reference clock of flight control software, the external link equipment of flight control software, and the functions of sensor data, actuator data, data communication interface, hardware driver, thread scheduling and so on. The simulation software technology enables the self-development stage of flight control software to get rid of the constraints of hardware simulator debugging conditions, quickly and conveniently verify the correctness of the timing logic and algorithm implementation of flight control software, greatly shorten the cycle of software development and unit test, save the development cost and improve the efficiency and quality of flight control software development.
