Abstract

The invention provides a full-digital simulation system based on satellite information flow. The system comprises an information flow simulation system, an integrated development environment, a clocksynchronization device and a real-time network communication device. The information flow simulation system comprises a chip-level simulation unit, a circuit-level simulation unit and a computer-likesimulation unit. The chip-level simulation unit directly runs the target code and performs instruction analysis, or a register interface and state rotation exist. The circuit-level simulation unit removes a register interface and takes an electric signal as main input and output. The computer-like simulation unit performs behavior-level simulation to replace the running target code. The information flow simulation system, the integrated development environment, the clock synchronization device and the real-time network communication device form a platform-level simulation unit, and the data flow of the platform-level simulation unit is consistent with the data flow of a real satellite.

Description

technical field [0001] The invention relates to the field of satellite technology, in particular to an all-digital simulation system based on satellite information flow. Background technique [0002] Digital construction is one of the key areas of science and technology development in my country. Foreign countries have paid more attention to digital simulation and started earlier, especially in the field of aerospace, which has accumulated a deep reserve of technical capabilities. For example, the National Aeronautics and Space Administration, Boeing, the European Space Research and Technology Center and the German IZT company all regard digital simulation as an important strategic guarantee and scientific and technological breakthrough point for institutions or groups. Even though foreign countries have invested huge financial, manpower and material resources in digital simulation technology, many catastrophic events have still been brought about because the simulation syst...
