Wherein the first dynamic link library file corresponds to a Simulink simulation model.
Specifically, in this embodiment, the first dynamic link library file may be loaded from a simulation model file derived by the Simulink simulation tool, so as to obtain a dynamic link library file corresponding to the Simulink simulation model.
For example, taking an unlitled _ win64.dll derived from Simulink as an example, in this embodiment, the unlitled _ win64.dll may be loaded by using a LoadLibrary to obtain a first dynamic link library file corresponding to the Simulink simulation model, that is, the unlitled _ win64.dll includes a plurality of interface functions, and specifically, the interface functions may be loaded by using GetProcAddress.
Step 102: and obtaining the source file at least according to the first dynamic link library file.
Wherein the source file corresponds to a Simulink simulation model.
Specifically, in this embodiment, the first dynamic link library file may be decompiled to obtain a source file corresponding to the Simulink simulation model.
For example, in this embodiment, at least the loaded untilted _ win64.dll is decompiled to obtain the source file abc.
Step 103: and compiling the source file to obtain at least a second dynamic link library file.
Wherein the second dynamic link library file corresponds to the target simulation model.
Specifically, in this embodiment, the source file may be compiled according to a simulation interface standard corresponding to the target simulation model, so as to obtain a second dynamic link library file corresponding to the target simulation model.

Step 104: and obtaining a simulation model file corresponding to the target simulation model at least according to the second dynamic link library file.

Specifically, the first description file may include one or more header files corresponding to the Simulink simulation model, such as a header file specified.h corresponding to specified _ wind 64.dll and other related header files rtwtypes.h.
The header file may also be understood as an interface description file, which includes information related to an input/output structure corresponding to the Simulink simulation model, and may also include other contents. The contents of the input and output structure bodies can be seen by looking at the unttled.h, the contents of the input and output structure bodies such as In1, Out1, errorStatus, unttled _ U, unttled _ Y and the like can be seen In the unttled.h, and each input and output structure body has a respective type, such as real _ T and the like. And rtwtypes.h may contain alias definition of type name and the like, for example, resl _ T type and the like may be reached by looking at rtwtypes.h.

Specifically, in this embodiment, the first dynamic link library file and the first description file may be decompiled to obtain a source file corresponding to the Simulink simulation model.
For example, in this embodiment, after a dll and h header file is exported and loaded from MATLAB, decompiling is performed on the loaded unlit _ win64.dll and header file unlit. h, where the unlit.h contains various exported functions, such as unlit _ M, untitled _ M _, unlit _ U, untitled _ Y, untitled _ initial, unlit _ step, and unlit _ terminate, and so on, so as to obtain the source file abc.
The unttled _ U is an input structure, unttled _ Y is an output structure, unttled _ initialize is an initialization interface, unttled _ step is an interface to be executed every other step, and the like.

For example, in the present embodiment, a 7Zip compression tool or other compression tools may be used to package the dynamic link library file and the description file corresponding to the FMU, so as to obtain the. FMU file of the FMU supporting the FMI interface standard.
In an implementation manner, when the source file is compiled to obtain at least the second dynamic link library file in step 103, the following specific steps may be implemented:
and compiling the source file by using a compiler under a preset compiling environment to obtain a second dynamic link library file.
Wherein the compilation environment corresponds to model parameters of the Simulink simulation model.
Specifically, in this embodiment, a compiling environment may be first set, where the set compiling environment corresponds to model parameters of a Simulink simulation model obtained in advance, and the model parameters at least include a number of model bits of the Simulink simulation model, and based on this, a parameter for executing a compiling command in the compiling environment may be set to correspond to the number of model bits of the Simulink simulation model, such as 32 bits or 64 bits.

For example, an independent simulation mode is characterized by me, namely only a single Simulink simulation model, and a joint simulation mode is characterized by cs, namely a plurality of Simulink simulation models, and compiling parameters corresponding to mode parameters of the Simulink simulation models are added in a compiler based on the fact that the Simulink simulation models are combined into a whole.
Based on this, in step 103, the compiler added with the compiling parameter corresponding to the mode parameter is used to compile the source file in the set compiling environment, specifically, the source file can be compiled according to the FMI interface standard, so as to obtain the dynamic link library file corresponding to the FMU.
