MATLAB: Stateflow – save coverage after closing model

coveragecumulative coveragestateflow

Can I somehow save coverage status of chart in Stateflow so I can retrieve it next time I open up the model in Matlab? I know the coverage representation (showed by green and red coloring) is saved across multiple simulation runs without having closed the model. But everything gets erased once I close and re-open the model.

You can use the 'cvmodelview' command with the saved coverage results (data) to retrieve the coverage status when you open the model again.

More information regarding this is available in the following articles:

Hi Jonatan,

I found an example of this by searching around, but this doesn't seem to be documented. Hopefully this at least helps to get you started with a shipping example, although you may have to play around with the code to figure out how to tailor this for your model.

model = 'slvnvdemo_cv_small_controller'; 
open_system(model) 
ssid = Simulink.ID.getSID('slvnvdemo_cv_small_controller/Saturation') 
f = SlCov.FilterEditor.getInstance(model) 
props = f.getProperties(ssid) 
f.setFilterByProp(props(2),'turn on filter for this block') % the second argument is the description for the filter 
f.save('filename') 
set_param(model,'CovFilter','filename') 
data = cvsim(model)

The other thing is: If you have an existing coverage filter file, you can add it programmatically to a cvtest object using the filter.fileName property. This is listed in the cvtest documentation .

MATLAB: Model coverage without using sim

This may be what you're looking for:

set_param(gcs,'SimulationCommand','Start')
set_param(gcs,'SimulationCommand','Pause')
set_param(gcs,'SimulationCommand','Stop')

This will allow you to continue processing commands while the model is playing as well as stop/pause the model whenever you desire.
