Is there any way to get a list of variables required for simulating a Simulink model?

I want to get a list of variables needed to run a Simulink simulation, for documentation purposes.

Hi Damon!

What you are looking for is 'Model Explorer'.

You can use the Model Explorer to view, modify, and add elements of Simulink® models and workspace variables. In the Model Explorer, you can get a list of variables that a model or block uses.

The Model Explorer lets you focus on specific elements (for example, blocks, signals, and properties) without navigating through the model or chart.

Take a look at the following link to know more about 'Model Explorer':

The below link specifically talks about 'finding variables used by model':

Hope the above suggestions help :)

Thank you Jyotish for your answer.

I had already seen the Model Explorer. But with the Model Explorer there is no summary list of variables needed to run a model, you have to go looking for the variables. For instance, I have an integrator block buried two levels down in a subsystem, and there is an Initial Condition specified by a variable in that integrator, and I don't see that variable in Model Explorer unless I go looking for it.

I was hoping to find a sort of summary table of variables needed to be initialized to run a model.

Also FYI the first link in your reply does not seem to work.

Maybe you could take a look at Simulink.findVars functionality. The following link takes you there:
