Examples

Get All Selectors

This example shows how to get all the selectors for an And block and then add a rule to justify or exclude a selector. Metric selectors can only be justified.

Load the model and set coverage settings

modelName = 'slvnvdemo_covfilt';
load_system(modelName);
set_param(modelName,'CovEnable','on','CovMetricStructuralLevel','MCDC');

First, get the block handle for the And block.

id = getSimulinkBlockHandle([modelName,'/Saturation']);

Get the selectors using the block handle.

sel = slcoverage.Selector.allSelectors(id)

sel = 

  1x10 heterogeneous Selector (BlockSelector, MetricSelector) array with properties:

    Description
    Type
    Id
    ConstructorCode

The block has ten selectors. You can index into each one to see their contents. In this example, you want to justify the sixth selector.

sel(6)

ans = 

  MetricSelector with properties:

     ObjectiveIndex: 2
       OutcomeIndex: 2
        Description: 'T outcome of input > upper limit in Saturate block "Saturation"'
               Type: DecisionOutcome
                 Id: 'slvnvdemo_covfilt:5'
    ConstructorCode: 'slcoverage.MetricSelector(slcoverage.MetricSelectorType.DecisionOutcome, 'slvnvdemo_covfilt:5', 2, 2)'

Create a justify rule, then create a filter object and add the rule to it.

rule = slcoverage.FilterRule(sel(6),'Expected result');
filt = slcoverage.Filter;
filt.addRule(rule);

Save the filter and generate a coverage report.

filt.save('metrfilter');
csim = cvsim(modelName);
csim.filter = 'metrfilter';
cvhtml('cov',csim,'-sRT=0');
