Create input port from .m file

I have bus signals , which is mentioned in .m file ,

I need to make the model with individual signal not as bus interface.

Any script to create inport as individual signal from the .mfile

Hi @Poornachandran,

I understand that you have some bus signals mentioned in a '.m' file. Further you need to make a model with individual signals as inports using a script.

You can follow the following method:

run('your_bus_signals_file.m');  % Using 'run' function to load the bus data
                                 % Replace with your actual .m file name 

modelName = 'BusSignalsModel';
new_system(modelName);
open_system(modelName);

% Here assuming that the signals are stored in a 'struct' called 'busData'
% You can change this accordingly if the data is stored otherwise.
signalNames = fieldnames(busData);

% Using a loop adding all inport blocks to the model
for i = 1:length(signalNames)
    
    % Creating inport using 'add_block' function
    blockName = ['Inport', num2str(i)];
    add_block('simulink/Sources/In1', [modelName, '/', blockName]);
    
    % Setting properties of the inport
    set_param([modelName, '/', blockName], 'Name', signalNames{i});
    set_param([modelName, '/', blockName], 'Position', [30, 30 + 50*i, 60, 50 + 50*i]);
end

save_system(modelName);
open_system(modelName);

You can refer to the following documentations for your reference:
