Package: slcoverage

Get selectors of all types


Use the slcoverage.Selector class with the allSelectors method to return all types of the selectors for a block.

This property is read-only.

Code used to create this selector object, returned as a character vector.

This property is read-only.

Description of the selector, returned as a character vector. Simulink® Coverage™ creates the description based on the selector.

This property is read-only.

Identifier of the model element, returned as character vector of the Simulink ID or handle.

This property is read-only.

Selector type, returned as a selector type of the corresponding selector.

Get all the selectors for the block. Then you can add a rule to exclude or justify a selector. (You can only justify metric selectors.)

Open the model and turn on coverage recording. Get all the selectors for the And block.

modelName = 'sldemo_lct_bus';
id = Simulink.ID.getSID('sldemo_lct_bus/slCounter/And');
sel = slcoverage.Selector.allSelectors(id)
s = 

  1×6 heterogeneous Selector (BlockSelector, MetricSelector) array with properties:


The block has six selectors. You can index into each one to see the content. The sixth selector is the metric selector that you want to justify.

ans = 

  MetricSelector with properties:

     ObjectiveIndex: 2
       OutcomeIndex: 2
        Description: 'F outcome of input port 2 in Logic block "And"'
               Type: ConditionOutcome
                 Id: 'sldemo_lct_bus:23'
    ConstructorCode: 'slcoverage.MetricSelector(slcoverage.MetricSelectorType.ConditionOutcome,'sldemo_lct_bus:23',2,2)'

Create a justify rule for the selector. Create a filter object and add the rule to it.

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

Save and run the filter.'metrfilter');
csim = cvsim(modelName);
csim.filter = 'metrfilter';
