sigrangeinfo - Collect signal range coverage information for model object

Syntax

Description

[min, max] = sigrangeinfo(cvdo, object) returns the minimum and maximum signal values output by the model component object within the cvdata object cvdo.

[min, max] = sigrangeinfo(cvdo, object, portID) returns the minimum and maximum signal values associated with the output port portID of the Simulink block object.

Input Arguments

cvdo	cvdata object
object	An object in the model or Stateflow chart that receives signal range coverage. Valid values for object include the following: Object Specification Description BlockPath Full path to a model or block BlockHandle Handle to a model or block slObj Handle to a Simulink API object sfID Stateflow ID sfObj Handle to a Stateflow API object {BlockPath, sfID} Cell array with the path to a Stateflow chart or atomic subchart and the ID of an object contained in that chart or subchart {BlockPath, sfObj} Cell array with the path to a Stateflow chart or atomic subchart and a Stateflow object API handle contained in that chart or subchart [BlockHandle, sfID] Array with a handle to a Stateflow chart or atomic subchart and the ID of an object contained in that chart or subchart
portID	Output port of the block object

Output Arguments

max	Maximum signal value output by the model component object within the cvdata object, cvdo. If object outputs a vector, min and max are also vectors.
min	Minimum signal value output by the model component object within the cvdata object, cvdo. If object outputs a vector, min and max are also vectors.

Alternatives

To collect signal range coverage for a model, using the GUI:

1. Open the model for which you want signal range coverage.

2. In the Model Editor, select Tools > Coverage Settings.

3. On the Coverage tab, under Coverage Metrics, select Signal Range Coverage.

4. Open the Results and Report tabs and specify the type of output that you need.

5. Click OK.

6. Simulate the model and view the results.

Examples

Collect signal range data for the Product block in the slvnvdemo_cv_small_controller model:

mdl = 'slvnvdemo_cv_small_controller';
open_system(mdl)
testObj = cvtest(mdl)                              %Create test spec object
testObj.settings.sigrange = 1;                     %Enable signal range coverage
data = cvsim(testObj)                              %Simulate the model
blk_handle = get_param([mdl, '/Product'], 'Handle');
[minVal, maxVal] = sigrangeinfo(data, blk_handle)  %Get signal range data
