cvsave(
saves all the tests (filename, model)cvtest objects)
and results (cvdata objects) related to model in
the text file filename.cvt. model is
a handle to or name of a Simulink® model.
cvsave(
saves all the results (filename, cvd)cvdata objects)
for the active model in the text file filename.cvt. cvsave also
saves information about any referenced
models.
cvsave(filename, saves multiple cvto1, cvto2,
...)cvtest objects
in the text file filename.cvt. cvsave also
saves information about any referenced
models.
cvsave( saves the test results stored in each element of filename, cell_array{
:})cell_array to
the file filename.cvt. Each element in cell_array contains
test results for a cvdata object.

Save coverage results for the slvnvdemo_cv_small_controller model
in ratelim_testdata.cvt:
model = 'slvnvdemo_cv_small_controller';
open_system(model);
cvt = cvtest(model);
cvd = cvsim(cvt);
cvsave('ratelim_testdata', model);Save cumulative coverage results for the Adjustable Rate Limiter
subsystem in the slvnvdemo_ratelim_harness model
from two simulations:
% Open model and subsystem
mdl = 'slvnvdemo_ratelim_harness';
mdl_subsys = ...
'slvnvdemo_ratelim_harness/Adjustable Rate Limiter';
open_system(mdl);
open_system(mdl_subsys);
% Create data files
t_gain = (0:0.02:2.0)';
u_gain = sin(2*pi*t_gain);
t_pos = [0;2];
u_pos = [1;1];
t_neg = [0;2];
u_neg = [-1;-1];
save('within_lim.mat','t_gain','u_gain','t_pos','u_pos', ...
't_neg', 'u_neg');
t_gain = [0;2];
u_gain = [0;4];
t_pos = [0;1;1;2];
u_pos = [1;1;5;5]*0.02;
t_neg = [0;2];
u_neg = [0;0];
save('rising_gain.mat','t_gain','u_gain','t_pos','u_pos', ...
't_neg', 'u_neg');
% Specify coverage options in cvtest object
testObj1 = cvtest(mdl_subsys);
testObj1.label = 'Gain within slew limits';
testObj1.setupCmd = 'load(''within_lim.mat'');';
testObj1.settings.mcdc = 1;
testObj1.settings.condition = 1;

testObj2 = cvtest(mdl_subsys);
testObj2.label = ...

testObj2.setupCmd = 'load(''rising_gain.mat'');';
testObj2.settings.mcdc = 1;
testObj2.settings.condition = 1;
testObj2.settings.decision = 1;
% Simulate the model with both cvtest objects
[dataObj1,simOut1] = cvsim(testObj1);
[dataObj2,simOut2] = cvsim(testObj2,[0 2]);
cumulative = dataObj1+dataObj2;
cvsave('ratelim_testdata',cumulative);
As in the preceding example, save cumulative coverage results
for the Adjustable Rate Limiter subsystem in the slvnvdemo_ratelim_harness model
from two simulations. Save the results in a cell array and then save
the data to a file:
% Open model and subsystem
mdl = 'slvnvdemo_ratelim_harness';
mdl_subsys = ...
'slvnvdemo_ratelim_harness/Adjustable Rate Limiter';
open_system(mdl);
open_system(mdl_subsys);
% Create data files
t_gain = (0:0.02:2.0)';
u_gain = sin(2*pi*t_gain);
t_pos = [0;2];
u_pos = [1;1];
t_neg = [0;2];
u_neg = [-1;-1];
save('within_lim.mat','t_gain','u_gain','t_pos','u_pos', ...
't_neg', 'u_neg');
t_gain = [0;2];
u_gain = [0;4];
t_pos = [0;1;1;2];
u_pos = [1;1;5;5]*0.02;
t_neg = [0;2];
u_neg = [0;0];
save('rising_gain.mat','t_gain','u_gain','t_pos','u_pos', ...
't_neg', 'u_neg');
% Specify coverage options in cvtest object
testObj1 = cvtest(mdl_subsys);
testObj1.label = 'Gain within slew limits';
testObj1.setupCmd = 'load(''within_lim.mat'');';
testObj1.settings.mcdc = 1;
testObj1.settings.condition = 1;
testObj1.settings.decision = 1;
testObj2 = cvtest(mdl_subsys);
testObj2.label = ...
'Rising gain that temporarily exceeds slew limit';
testObj2.setupCmd = 'load(''rising_gain.mat'');';
testObj2.settings.mcdc = 1;
testObj2.settings.condition = 1;
testObj2.settings.decision = 1;
% Simulate the model with both cvtest objects
[dataObj1,simOut1] = cvsim(testObj1);
[dataObj2,simOut2] = cvsim(testObj2,[0 2]);
% Save the results in the cell array
cov_results{1} = dataObj1;
cov_results{2} = dataObj2;
% Save the results to a file
cvsave('ratelim_testdata', cov_results{ :});
Use the coverage settings to save cumulative coverage results for a model:
Open the model for which you want to save cumulative coverage results.
In the Model Editor, select Model Settings on the Modeling tab.
On the Coverage pane of the Configuration Parameters dialog box, select Enable coverage analysis.
On the Coverage > Results pane, select Save last run in workspace variable.
Click OK to close the Configuration Parameters dialog box and save your changes.
Simulate the model and review the results.
