Retrieve lookup table coverage information from cvdata object

Syntax

Description

[covInfo](#brxo36q-1-coverage) = tableinfo([cvdo](#brxo36q-1%5Fsep%5Fbrxo2jj-1-cvdo),[modelObject](#brxo36q-1%5Fsep%5Fbtrlw80-object)) returns lookup table coverage results from thecvdata objectcvdo for the model componentmodelObject.

[covInfo](#brxo36q-1-coverage) = tableinfo([cvdo](#brxo36q-1%5Fsep%5Fbrxo2jj-1-cvdo),[modelObject](#brxo36q-1%5Fsep%5Fbtrlw80-object),[ignoreDescendants](#brxo36q-1%5Fsep%5Fmw%5Ffeb2a172-08b8-4e3b-b2bb-6c8d51d75f21)) returns lookup table coverage results for modelObject, depending on the value of ignoreDescendants.

[[covInfo](#brxo36q-1-coverage),[exeCounts](#brxo36q-1-exeCounts)] = tableinfo([cvdo](#brxo36q-1%5Fsep%5Fbrxo2jj-1-cvdo),[modelObject](#brxo36q-1%5Fsep%5Fbtrlw80-object)) returns lookup table coverage results and the execution count for each interpolation/extrapolation interval in the lookup table blockmodelObject.

[[covInfo](#brxo36q-1-coverage),[exeCounts](#brxo36q-1-exeCounts),[brkEquality](#brxo36q-1-brkEquality)] = tableinfo([cvdo](#brxo36q-1%5Fsep%5Fbrxo2jj-1-cvdo),[modelObject](#brxo36q-1%5Fsep%5Fbtrlw80-object)) returns lookup table coverage results, the execution count for each interpolation/extrapolation interval, and the execution counts for breakpoint equality.

Collect lookup table coverage for theslvnvdemo_cv_small_controller model and determine the percentage of interpolation/extrapolation intervals coverage collected for the Gain Table block in the Gain subsystem:

mdl = 'slvnvdemo_cv_small_controller'; open_system(mdl) %Create test spec object testObj = cvtest(mdl) %Enable lookup table coverage testObj.settings.tableExec = 1; %Simulate the model data = cvsim(testObj) blk_handle = get_param([mdl, '/Gain/Gain Table'], 'Handle'); %Retrieve l/u table coverage cov = tableinfo(data, blk_handle) %Percent MCDC outcomes covered percent_cov = 100 * cov(1) / cov(2)

Input Arguments

collapse all

Coverage data, specified as a cvdata object.

Data Types: cvdata

Model object, specified as a character array, string array, Simulink® handle, Stateflow® ID, or cell array.

To specify a model object, such as a block or a Stateflow chart, use one of these formats:

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

Whether to ignore descendants in coverage results, specified as a numeric or logical1 (true) or 0 (false), where:

0 (false) includes coverage results of descendant objects.
1 (true) ignores coverage results of descendant objects.

Data Types: single | double | logical

Output Arguments

collapse all

Coverage information, returned as a two-element array of the form[covered_intervals,total_intervals] if cvdo contains lookup table coverage data, or an empty array if it does not.

covered_intervals	Number of interpolation/extrapolation intervals satisfied formodelObject
total_intervals	Total number of interpolation/extrapolation intervals formodelObject

Data Types: double

Execution count, returned as an array of doubles. exeCounts contains execution counts for each interpolation and extrapolation interval in the lookup table block.exeCounts has one more entry in each dimension than the lookup table block.

Data Types: double

Breakpoint equality flag, returned as a cell array. Each cell contains a vector which identifies the number of times during simulation the lookup table block input is equivalent to a breakpoint value. Each vector represents the breakpoints along a different lookup table dimension.

Data Types: cell

Alternatives

Use the coverage settings to collect lookup table coverage for a model:

Open the model.
In the Model Editor, select Model Settings on theModeling tab.
On the Coverage pane of the Configuration Parameters dialog box, selectEnable coverage analysis.
Under Coverage metrics, select Lookup Table.
Click OK to close the Configuration Parameters dialog box and save your changes.
Simulate the model by clicking theRun button and review the results.
