Examples
View Condition Coverage Data
This example shows how to view condition coverage for a block in your model.
Load the model.
modelName = 'slvnvdemo_cv_small_controller';
load_system(modelName);
Configure the coverage settings for the model by using a Simulink.SimulationInput
object.
simIn = Simulink.SimulationInput(modelName); simIn = simIn.setModelParameter('CovEnable','on'); simIn = simIn.setModelParameter('CovMetricStructuralLevel','MCDC'); simIn = simIn.setModelParameter('CovSaveSingleToWorkspaceVar','on'); simIn = simIn.setModelParameter('CovSaveName','covData');
Simulate the model by passing simIn
as the input to sim
.
simOut = sim(simIn); covData = simOut.covData;
View the condition coverage results for the Logic block in the Gain subsystem by calling conditioninfo
with the block path.
condCov = conditioninfo(covData,[modelName,'/Gain/Logic'])
condCov = 2 4
conditioninfo
returns an array with two scalars. The first value is the number of satisfied condition outcomes, and the second value is the number of total condition outcomes. Use these to determine the percentage of satisfied condition outcomes for the Logic block.
percentCondCov = 100 * condCov(1) / condCov(2)
percentCondCov = 50
