[0042] Specifically, the compilation tool links_rtlnx_grt is imported into the software, and after the environment configuration, the model is compiled to obtain .out files and xml files that can be run in the Linux environment.

[0043] Step S3, loading the compiled .fmu file and .out file into the target machine, and setting simulation parameters;

[0044] Specifically, import the .fmu file compiled in step S1 and the .out file compiled in step S2 into the upper computer simulation control software RTSimPlus; then set the running step size of the comparison software model to 0.001s, the running time to 10s, and the specified running CPU core number to 1; then set the running step size of the Mworks model to 0.001s, the running time to 10s, and the specified running CPU core number to 2.

[0045] Step S4, obtaining the operation result;

[0046] Specifically, Figure 2 As shown in the figure, after the operation is completed, the simulation target machine simultaneously outputs the operation efficiency information of the Mworks model and the comparison software model, including the maximum step length, the minimum step length, the maximum single-step operation time, the minimum single-step operation time, and the average single-step operation time.
