Manage Coverage Data

Access, manage, and aggregate coverage results

You can use Simulink^® Coverage™ to access, manage, and aggregate coverage results. You can also assess testing completeness by aggregating coverage data from multiple test runs.

Objects

`cvdata`	Access Simulink Coverage data in the MATLAB workspace
`cv.cvdatagroup`	Collection of `cvdata` objects

Functions

Store and Retrieve Coverage Results

`cvload`	Load coverage tests and stored results into memory
`cvsave`	Save coverage settings and results to file
`cvresults`	Returns active coverage data, clears and loads active coverage data from a file

Query Coverage Results

`executioninfo`	Retrieve execution coverage information from `cvdata` object
`conditioninfo`	Retrieve condition coverage information from `cvdata` object

Topics

Access, Manage, and Aggregate Coverage Results
Access, manage, and aggregate coverage results from the Results Explorer after you collect coverage.
Cumulative Coverage Data
Collect cumulative coverage from successive simulations.
Analyze Coverage Data Using A Script
Retrieve specific coverage information after simulation using MATLAB^® commands.
Collect Coverage in Tests (Simulink Test)
Use coverage measurement to assess the extent of your tests.
Extracting Detailed Information from Coverage Data
This example shows how coverage utility commands can be used to extract information for an individual subsystem, block, or Stateflow® object from cvdata objects.

Featured Examples

Basic Operation of the Model Coverage Tool

Use the Configuration Parameters dialog to enable coverage for a Simulink® model and adjust the type of information that is reported.

Open Model

Perform Operations on Coverage Data

Use the overloaded operators +, *, and - to combine coverage results into a union, intersection, or set difference of results.
