Examples

collapse all

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

Open the model. Specify coverage settings and turn on coverage recording.

modelName = 'slcoverage_lct_bus';
open_system(modelName);
set_param(modelName,'CovMetricStructuralLevel','MCDC','RecordCoverage','on');

Select blocks with block type 'RelationalOperator' to add a filter rule for. 

bl = slcoverage.BlockSelector(slcoverage.BlockSelectorType.BlockType,'RelationalOperator');

Create a filter object, create a rule, and add the rule to the filter. This rule excludes the selection from coverage analysis.

filt = slcoverage.Filter;
rule = slcoverage.FilterRule(bl,'Tested elsewhere',slcoverage.FilterMode.Exclude);
filt.addRule(rule);
