A method of aeronautical electrical interface circuit design and simulation analysis based on Saber

In this paper, the idea of model-based system engineering is adopted. For the aircraft's electrical interface circuit, Saber software is used to carry out "device-circuit"modeling and simulation, and the corresponding hardware circuits are verified and compared. Simulation and hardware verification results show that the modeling method designed in this paper can better integrate the rapidity of modeling and the accuracy of the simulation. In order to deal with the "neck jam"problem, domestic components are widely used today. This study provides a solution for optimizing process design and improving the degree of digitalization and provides model support for Model Based Systems Engineering (MBSE) in China's aviation field.
