Examples

collapse all

Create an options object and set several parameters.

Create an opts option for the sldvdemo_cruise_control model: 

opts = sldvoptions;
opts.AutomaticStubbing = 'on';
opts.Mode = 'TestGeneration';
opts.ModelCoverageObjectives = 'MCDC';
opts.ReportIncludeGraphics = 'on';
opts.SaveHarnessModel = 'off';
opts.SaveReport = 'off';
opts.TestSuiteOptimization = 'LongTestcases';

Get the options object for the sldvdemo_cruise_control model. You can use deepCopy method if you want to create a standalone version of sldvoptions but would like to start with copy of options from the model configuration set.

Open the model sldvdemo_cruise_control in command prompt:

openExample('sldv/CruiseControlTestGenerationExample',...
'supportingFile', 'sldvdemo_cruise_control');
optsModel = sldvoptions(bdroot);
optsCopy = optsModel.deepCopy;
optsCopy.MaxProcessTime = 120;

MaxProcessTime

Specify the maximum time (in seconds) that Simulink Design Verifier spends analyzing a model.

You can set the value of maximum analysis time to the value that you are willing to provide to the analysis. You can also stop the analysis at any time.

int32

300 (default)

MaxTestCaseSteps

Specify the maximum number of simulation steps when attempting to satisfy a test objective.

The analysis uses the MaxTestCaseSteps parameter during certain parts of the test generation analysis to bound the number of steps that test generation uses. When you set a small value for this parameter, the parts of the analysis that are bounded completes in less time. When you set a larger value, the bounded parts of the analysis take longer, but it is possible for these parts of the analysis to generate longer test cases.

To achieve the best performance, set the MaxTestCaseSteps parameter to a value large enough to bound the longest required test case, even if the test cases that are ultimately generated are longer than this value.

When you set the TestSuiteOptimization parameter to 'LongTestcases', the analysis uses successive passes of test generation to extend a potential test case so that it satisfies more objectives. The analysis applies the MaxTestCaseSteps parameter to each individual iteration of test generation.

This parameter is enabled when Mode is set to 'TestGeneration'.
