Hello all,
I would like to collect certains subset of signals from my complex model, to do so I am following this link. I am interested only in the subset since the model logs more signals than I am interested in at this moment, but I don't want to disable all the logged signals of the model.
My code looks like this
mdl = 'myModelA';
% Get model info regarding to which signals are currently being logged
ov = Simulink.SimulationData.ModelLoggingInfo(mdl);
% Define those signals that we are interested on replacing to be logged
blkPort = 1;
so(1) = Simulink.SimulationData.SignalLoggingInfo([mdl '/|(x[n]+r_thermal[n])*Glna|'],blkPort);
so(2) = Simulink.SimulationData.SignalLoggingInfo([mdl '/was_abort_triggered_monitoring'],blkPort);
so(3) = Simulink.SimulationData.SignalLoggingInfo([mdl '/validACQ'],blkPort);
so(4) = Simulink.SimulationData.SignalLoggingInfo([mdl '/PER_ACQ'],blkPort);
% Replace original signals to debug by the ones in so vector
ov.Signals = so;
% apply this object so the model
for currentPower=1:2
iterationOutput = sim(mdl);
simulationOutput{currentPower} = iterationOutput;
clear "iterationOutput"
Reading the link it's there stated that Simulink saves the settings when you save the model. Does this mean that I have to save the model before simulating the model?

Hi Javier,
Yes, you will have to save the model before simulating so as to lock the model override object settings.
