MATLAB: How to prevent an opened model from navigating back to the top level after running simulation with Coverage Analysis in Simulink Verification and Validation R2013b

analysiscoveragemodelnavigationsimulinkSimulink CheckSimulink Coverage

I have my Simulink model opened and navigated to a lower level. I ran the simulation with Coverage Analysis enabled. After the simulation, my model window navigated back to the top level. How can I make the model window stay at the level I am at before the simulation?

This is a behavior in old releases before MATLAB R2014a. In newer releases, the Simulink window will stay at the same level you are at after the simulation run.

Therefore, upgrading to a newer version is one of the choices to overcome this inconvenience. For MATLAB R2013b and earlier, a workaround would be invoking the simulation from a test script and programmatically navigate to the desired model level. For example, in the following code, the 'sldemo_clutch' model is simulated and analyzed for coverage. Before the simulation, we are focusing inside the subsystem 'Unlocked'. Simulation runs and reverts the navigation level to the top. We re-navigate back to the 'Unlocked' subsystem by using the 'open_system' command again. Since the simulation takes a while and the reverting to top model level happens after the simulation, we use the 'pause' command to wait and navigate back after the reverting.

mdl = 'sldemo_clutch';
open_system(mdl);
set_param(mdl, 'RecordCoverage','on');
set_param(mdl, 'CovMetricSettings','dcmtrzoib');
open_system([mdl,'/Unlocked']);
set_param(mdl, 'SimulationCommand', 'start'); % run simulation
pause(1); % wait for simulation and the navigation reverting to finish
open_system([mdl,'/Unlocked']); % navigate back to the subsystem

MATLAB: How to programmatically replace a referenced model with a Subsystem in Simulink

Assuming that you have a 'parent.slx' model which references a model 'child.slx' (whose block name is 'Model' in the parent Simulink model), use either of the following options:

>> open_system('parent');

>> add_block('built-in/Subsystem',['parent/mySub']);

>> load_system('child');

>> Simulink.BlockDiagram.copyContentsToSubsystem('child',['parent/mySub']);

>> pos = get_param('parent/Model','position');

>> delete_block('parent/Model');

>> set_param('parent/mySub','position',pos);

>> open_system('parent');

>> load_system('child');

>> convert2subsys('child');

>> add_block('child/Subsystem','parent/mySub');

>> pos = get_param('parent/Model','position');

>> delete_block('parent/Model');

>> set_param('parent/mySub','position',pos);

>> close_system('child',0);

where 'convert2subsys' is defined at the following link:

MATLAB: Run a simulink model for a certain amount of time and pause

If you know the times that you want to stop and restart it at, could you maybe use the SimState to resume the simulation, something like this?

open('sldemo_bounce');
mdl = bdroot;
set_param(mdl, 'SaveFinalState', 'on', 'FinalStateName',...
 [mdl 'SimState'],'SaveCompleteFinalSimState', 'on')
[t1, Y1] = sim(mdl, [0 15]);
plot(t1,Y1,'b');
set_param(mdl, 'LoadInitialState', 'on', 'InitialState',...
[mdl 'SimState']);
[t2, Y2] = sim(mdl, [15 25]);
hold on; plot(t2,Y2,'r');
set_param(mdl, 'LoadInitialState', 'off');
