Digital simulation test platform design method for satellite service software

The invention discloses a digital simulation test platform design method for satellite service software, which comprises the following steps of: simulating a hardware environment of satellite-borne software by using QEMU software, creating a digital simulation environment with the same function as real hardware, simulating a CPU (Central Processing Unit), a memory, an interrupt and other external equipment, and modifying a boot loader module; based on the target architecture, selecting a corresponding cross compiling tool, and configuring related parameter settings of a compiler in a Linux environment; generating the satellite-borne software code into a binary executable file capable of running in a target architecture by utilizing the cross compiling tool chain; determining that configuration of related equipment and the like in a test environment is correct, starting a QEMU digital simulation test environment, loading an executable file of a specified target architecture, and performing satellite-borne soft
