Unable to generate .dll file of simulink model to be used in amesim using the command sl2amecosim

Hello,

I have a simulink black box model with S-function integrated, I want to use the simulink model in amesim as a submodel. I am using the command sl2amecosim to generate the library but unsuccessful. Please find the error below

***

sl2amecosim('Continental_CAirS_v2', 'CAIrs_SL2AME','auto')

The function is unable to read the file ASU_sf.h even though it's provided in the folder

matlab version : 2018A, 2018B

amesim version : 2019.2

Any help would be appreciated

Hello Ahmed,

The error message you are encountering indicates that the compiler cannot find the 'ASU_sf.h' header file, which is required for the compilation process. This file is likely associated with an S-function within your Simulink model. Ensure that the ASU_sf.h file exists in the expected directory. If the file is missing, you need to locate it and place it in the correct directory. If the file exists, ensure that the file path is correctly set so that the compiler can find it. The file path needs to be included in the compiler's include directories.

Here's a general code snippet to add a directory to the MATLAB path, which you can modify with the correct path where ASU_sf.h is located:

>> addpath('path_to_directory_containing_ASU_sf_header');

You need to replace 'path_to_directory_containing_ASU_sf_header' with the actual path to the directory containing the ASU_sf.h file. After updating the path, attempt to run 'sl2amecosim' again.

To know more about the 'addpath' function, refer its documentation here: https://in.mathworks.com/help/matlab/ref/addpath.html

Hope this helps
