cvsave

Save coverage tests and results to file

Syntax

cvsave(filename, model)
cvsave(filename, cvd)
cvsave(filename, cvto1, cvto2, ...)
cvsave(filename, cell_array{ :})

Description

cvsave(filename, model) saves all the tests (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(filename, cvd) saves all the results (cvdata objects) for the active model in the text file filename.cvt. cvsave also saves information about any referenced models.

cvsave(filename, cvto1, cvto2, ...) saves multiple cvtest objects in the text file filename.cvt. cvsave also saves information about any referenced models.

cvsave(filename, cell_array{ :}) saves the test results stored in each element of cell_array to the file filename.cvt. Each element in cell_array contains test results for a cvdata object.

Input Arguments

filename

Character vector containing the name of the file in which to save the data. cvsave appends the extension .cvt to the name of the file when saving it.

model

Handle to a Simulink model

cvd

cvdata object

cvto

cvtest object

cell_array

Cell array of cvtest objects

Examples

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;
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]);

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{ :});

Alternatives

Use the coverage settings to save cumulative coverage results for a model:

  1. Open the model for which you want to save cumulative coverage results.

  2. In the Model Editor, select Analysis > Coverage > Settings.

  3. On the Coverage pane of the Configuration Parameters dialog box, select Enable coverage analysis.

  4. On the Coverage > Results pane, select Save last run in workspace variable.

  5. Click OK to close the Configuration Parameters dialog box and save your changes.

  6. Simulate the model and review the results.
