How can I display the SimulationStatus in a simulink model and/or GUI?

For example the user wants to see whether the simulation is running, or stopped. I know I can get_param('sys','SimulationStatus') to obtain the parameter, but how can I continuously have that updated on my simulink model or in a GUI? I know I could probably create a block mask that changes dynamically using callbacks, but I don't know the correct syntax to do so.

Thanks!

Hi MaSk,

you could create a textbox:

figure()
ann = annotation('textbox',...
                 [0 0 0.3 0.1]);

and then write the simulation state to the textbox using the model callbacks (Model Properties >> Callbacks).

To do so, insert following code in each callback (PreLoadFcn, PostLoadFcn, ...):

ann.set('string',get_param('sys','SimulationStatus'))

Remark: using disp() to write directly to the Command Window instead of a textbox seems not to work anymore (tried it with MATLAB 2016b).

Thank you, this works well! What I ended up solving my problem with was within the mask display window executing the following:

y = get_param('sys','SimulationStatus');

if strcmp(y, 'stopped')

   image('SimStopped.jpg')

elseif strcmp(y,'running')

    image('SimRunning.jpg')
else strcmp(y,'paused')
    disp('paused')
end

I just created images that represented what I wanted to display in the box.

Thanks for the help!
