How to disable the display of coverage report once the simulation is stopped

I am in a situation where I need to collect cumulative coverage after multiple simulation restarts. Right now, whenever I hit the stop button, the coverage report is getting generated and it consumes some time, instead am wondering if I can disable the coverage report geneartion and instead save it to a workspace variable and generate the reports at once after all my runs?

Hi Prasad,

It is not possible to disable coverage report in the model configuration settings or in the ‘Simulink Coverage’ app as far as I know. However, you can store the coverage data in the workspace for each run if the coverage analysis is done via a script. This data can then be used to generate the report at the end of the iterations.

Here is an example of the implementation:

load_system('slvnvdemo_ratelim_harness'); 

%Set up the coverage parameters 
paramStruct.CovEnable = 'on'; 
paramStruct.CovScope = 'Subsystem'; 
paramStruct.CovPath = '/Adjustable Rate Limiter'; 
paramStruct.StartTime = '0.0'; 
paramStruct.StopTime = '2.0';  

%setup a test 
load within_lim.mat; 

%loop to simulate and store coverage data 
for i = 1:5 
    
    % Generate a unique coverage data name for each iteration 
    covSaveName = sprintf('covData%d', i); 
    % Set the coverage save name parameter 
    paramStruct.CovSaveName = covSaveName;  

    % Simulate the model using |sim| with |paramStruct| as an additional input 
    % to collect coverage data using the specified parameters. 
    simOut = sim('slvnvdemo_ratelim_harness',paramStruct); 

    % Use |cvsave| to save the coverage results. The first input is the name of 
    % the coverage data file, and the second input is the |cvdata| object. 
    cvsave(covSaveName,covData); 
end 

%generate the report 
cvhtml('covReport',covData1,covData2,covData3,covData4,covData5,'-sRT=1');
