The current software virtual simulation method mainly comprises source code simulation and binary level simulation. The source code emulation is completed by recompiling the software source code on an emulation platform and realizing similar functions through binary codes under different architectures. Binary simulation is realized by virtual hardware and running a target binary software code on the virtual hardware, and currently, Simics is mainly adopted to perform full-system simulation, but the simulation is performed based on a factory closed-source technology, so that the complexity and flexibility of a system are limited.

In addition to the target hardware processing device, an I/O device of the target hardware needs to be simulated. Because the application program can access various real I/O hardware devices when running on the real hardware in the target hardware, in order to support the device access codes, the device hardware virtual module 2 simulates corresponding hardware or a driver to support the running simulation of the target application program. The simulated I/O device hardware includes, for example, network devices, communication devices, storage devices, etc.

c. the compatibility higher than the simulation level of the source code is provided, and the compatibility of each part of the simulated system is greatly improved because the target binary code is directly adopted for running, so that the source code-level simulation object and the simulated object without the source code can be unified to the binary level for comprehensive simulation, and the problem of simulation of the part without the source code in the simulated system on partial occasions is solved;
d. the method is realized based on the open source virtual machine technology, can realize deeper customization and simulation, and can be conveniently modified and expanded;
