Simulate model by using input data


outData = slvnvruntest(model, dataFile) simulates model by using all the test cases in dataFile. outData is an array of Simulink.SimulationOutput objects. Each array element contains the simulation output data of the corresponding test case.

outData = slvnvruntest(model, dataFile, runOpts) simulates model by using all the test cases in dataFile. runOpts defines the options for simulating the test cases.

[outData, covData] = slvnvruntest(model, dataFile, runOpts) simulates model by using the test cases in dataFile. When the runOpts field coverageEnabled is true, the Simulink® Coverage™ software collects model coverage information during the simulation. slvnvruntest returns the coverage data in the cvdata object covData.

Input Arguments

collapse all

The Simulink model to simulate.

Name of the data file or structure that contains the input data. You can generate dataFile with Simulink Design Verifier™ software, or by running the slvnvlogsignals function.

A structure whose fields specify the configuration of slvnvruntest.



Test case index array to simulate from dataFile. If testIdx is [], slvnvruntest simulates all test cases.

Default: []


If true, specifies that the Simulink Coverage software collects model coverage data during simulation.

Default: false


cvtest object for collecting model coverage. If [], slvnvruntest uses the existing coverage settings for model.

Default: []

Output Arguments

Each Simulink.SimulationOutput object has the following fields.

Field NameDescription


Simulation time


State data


Output signal data


Signal logging data for:

  • Signals connected to outports

  • Signals that are configured for logging on the model

cvdata object that contains the model coverage data collected during simulation.


Analyze the Model and Examine the Output Data with the Simulation Data Inspector

% Analyze the sldemo_mdlref_basic model and log the input signals to the CounterA Model block:
loggedData = slvnvlogsignals('sldemo_mdlref_basic/CounterA');

% Using the logged signals, simulate the model referenced in the Counter block (sldemo_mdlref_counter):
runOpts = slvnvruntestopts;
runOpts.coverageEnabled = true;
[ outData ] = slvnvruntest('sldemo_mdlref_counter',...
    loggedData, runOpts);

% Examine the output data from the first test case using the Simulation Data Inspector:
Simulink.sdi.createRun('Test Case 1 Output', 'namevalue',...
    {'output'}, {outData(1).find('logsout_slvnvruntest')});


The dataFile that you create with a Simulink Design Verifier analysis or by running slvnvlogsignals contains time values and data values. When you simulate a model by using these test cases, you might see missing coverage. This issue occurs when the time values in the dataFile are not aligned with the current simulation time step due to numeric calculation differences. You see this issue more frequently with multirate models—models that have multiple sample times.
