Hello Nikhil,

To create a MIL automation script according to the specified requirements, follow these steps:

• Access the 'Signal Editor' block using the 'set_param' function, as demonstrated in the code snippet below. Additional details about this function can be found in this documentation: https://www.mathworks.com/help/releases/R2023a/simulink/slref/set_param.html .

    blockPath = [modelName '/Signal Editor'];  
    newSignalDataFile = 'new_signal_file.mat'; 
    set_param(blockPath, 'Filename', newSignalDataFile); 

• Import a .MAT file using the 'load' function, as shown in the code snippet below. More details about this function can be found in this documentation:https://www.mathworks.com/help/releases/R2023a/matlab/ref/load.html .

    load("fileName.mat"); 

• Import a .XLSX file using the 'readtable' function, as illustrated in the code snippet below. More details about this function can be found in this documentation:https://www.mathworks.com/help/releases/R2023a/matlab/ref/readtable.html .

    T = readtable('sample_data.xlsx','ReadRowNames',true); 

• The test manager can be accessed by creating an instance of 'sltest.testmanager'. For more details on how to access functions and classes within it, as well as how to create and run test cases, refer to this documentation:https://www.mathworks.com/help/releases/R2023a/sltest/ug/create-and-run-test-cases-with-scripts.html .
