executioninfo

Retrieve execution coverage information from cvdata object

Syntax

coverage = executioninfo(cvdo, object)
coverage = executioninfo(cvdo, object, mode)
coverage = executioninfo(cvdo, object, ignore_descendants)
[coverage, description] = executioninfo(cvdo, object)


Description

coverage = executioninfo(cvdo, object) returns execution coverage results from the cvdata object cvdo for the model component specified by object.

coverage = executioninfo(cvdo, object, mode) returns execution coverage results from the cvdata object cvdo for the model component specified by object for the simulation mode mode.

coverage = executioninfo(cvdo, object, ignore_descendants) returns execution coverage results for object, depending on the value of ignore_descendants.

[coverage, description] = executioninfo(cvdo, object) returns execution coverage results and text descriptions of execution points associated with object.

Input Arguments

cvdo	cvdata object
object	The object argument specifies an object in the model or Stateflow® chart that received execution 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 from a singly instantiated Stateflow chart {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 subchart and a Stateflow object API handle contained in that chart or subchart {BlockHandle, sfID} Cell array with a handle to a Stateflow chart or atomic subchart and the ID of an object contained in that chart or subchart When specifying an S-function block, valid values for object include the following: Object Specification Description {BlockPath, fName} Cell array with the path to an S-Function block and the name of a source file. {BlockHandle, fName} Cell array with an S-Function block handle and the name of a source file. {BlockPath, fName, funName} Cell array with the path to an S-Function block, the name of a source file, and a function name. {BlockHandle, fName, funName} Cell array with an S-Function block handle, the name of a source file an a function name. For coverage data collected during Software-in-the-Loop (SIL) mode or Processor-in-the-Loop (PIL) simulation mode, valid values for object include the following: Object Specification Description {fileName, funName} Cell array with the name of a source file and a function name. {Model, fileName} Cell array with a model name (or model handle) and the name of a source file. {Model, fileName, funName} Cell array with a model name (or model handle), the name of a source file, and a function name.
mode	The mode argument specifies the simulation mode for coverage. Valid values for mode include the following: Object Specification Description 'Normal' Model in Normal simulation mode. 'SIL' (or 'PIL') Model in Software-in-the-Loop (SIL) or Processor-in-the-Loop (PIL) simulation mode. 'ModelRefSIL' (or 'ModelRefPIL') Model reference in Software-in-the-Loop (SIL) or Processor-in-the-Loop (PIL) simulation mode. 'ModelRefTopSIL' (or 'ModelRefTopPIL') Model reference in Software-in-the-Loop (SIL or Processor-in-the-Loop (PIL) simulation mode with code interface set to top model.
ignore_descendants	Specifies to ignore the coverage of descendant objects if ignore_descendants is set to 1.

Output Arguments

coverage	The value of coverage is a two-element vector of the form [covered_outcomes total_outcomes].coverage is empty if cvdo does not contain execution coverage results for object. The two elements are: covered_outcomes Number of execution outcomes satisfied for object total_outcomes Number of execution outcomes for object
description	description is a structure array containing the following fields: decision.text Structure array describing block execution counts isFiltered Whether the block is filtered filterRationale The filtering rationale justifiedCoverage The justified decision conditions isJustified Whether the block is justified

Examples

Open the slvnvdemo_cv_small_controller model and create the test specification object testObj. Enable execution coverage for slvnvdemo_cv_small_controller and execute testObj using cvsim. Use executioninfo to retrieve the execution coverage results for the Saturation block and determine the percentage of execution outcomes covered:

mdl = 'slvnvdemo_cv_small_controller';
open_system(mdl)
testObj = cvtest(mdl)
data = cvsim(testObj)
blk_handle = get_param([mdl, '/Saturation'], 'Handle');
cov = executioninfo(data, blk_handle)
percent_cov = 100 * cov(1) / cov(2)

Alternatives

Use the coverage settings to collect and display execution coverage results:

1. Open the model.

2. In the Model Editor, select Model Settings on the Modeling tab.

3. On the Coverage pane of the Configuration Parameters dialog box, select Enable coverage analysis.

4. Under Coverage metrics, select Block Execution as the structural coverage level.

5. On the Coverage > Results pane, specify the output you need.

6. Click OK to close the Configuration Parameters dialog box and save your changes.

7. Simulate the model and review the results.
