Exporting Names of Inputs and Outputs of a Simulink Model to a Excel File

Question

How Can I Export Names of All Inputs and Outputs of a Simulink Model to a Excel File?

I have tried to code a script file but it is nothing more than scratch. I am expecting to import all the inputs and outputs of my Simulink model.

Answer 1

This is fairly simple

model_name = 'port_test';

mdl = load_system(model_name);

inputs = find_system(mdl,'BlockType','Inport');
input_names = arrayfun(@(x) get_param(x,'Name'), inputs,'UniformOutput',false);

outputs = find_system(mdl,'BlockType','Outport');
output_names = arrayfun(@(x) get_param(x,'Name'), inputs,'UniformOutput',false);

• load_system opens the system of interest and returns the model handle
• find_system is a powerful function (backwards compatible with many versions of MATLAB which will search through a model for blocks/items that match. It will return an array of handles for each object found
• arrayfun performs a function on an array of items.
• get_param is used to get the name of each of the items found by find_system

Two cell arrays (input_names and output_names) will be created and will contain a list of all the inputs and output blocks in the top level of the model specified by model_name.

For writing out to a spreadsheet, I'd suggest using the power of the writetable function.

Could be something as simple as this

input_table = table(input_names);
writetable(input_table,[model_name '.xlsx'],'Sheet','Inputs');

output_table = table(input_names);
writetable(output_table,[model_name '.xlsx'],'Sheet','Outputs','WriteMode','append');
