sigsizeinfo

Retrieve signal size coverage information from cvdata object

Syntax

[min, max, allocated] = sigsizeinfo(data, object) [min, max, allocated] = sigsizeinfo(data, object, portID)

Description

[min, max, allocated] = sigsizeinfo(data, object) returns the minimum, maximum, and allocated signal sizes for the outputs of model component object within the coverage data object data, if object supports variable size signals.

[min, max, allocated] = sigsizeinfo(data, object, portID) returns the minimum and maximum signal sizes associated with the output port portID of the model component object.

Input Arguments

data

cvdata object

object

An object in the model or Stateflow^® chart that receives signal size coverage. Valid values for object include the following:

Object Specification	Description
`BlockPath`	Full path to a Simulink^® model or block
`BlockHandle`	Handle to a Simulink 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}`	Cell 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 number of the model component object

Output Arguments

`max`	Maximum signal size output by the model component `object` within the `cvdata` object `data`. If `object` has multiple outputs, `max` is a vector.
`min`	Minimum signal size output by the model component `object` within the `cvdata` object `data`. If `object` has multiple outputs, `min` is a vector.
`allocated`	Allocated signal size output by the model component `object` within the `cvdata` object `data`. If `object` has multiple outputs, `allocated` is a vector.

Examples

Collect signal size coverage data for the Switch block in the sldemo_varsize_basic model:

mdl = 'sldemo_varsize_basic';
open_system(mdl);
%Create test spec object
testObj = cvtest(mdl);
%Enable signal size coverage
testObj.settings.sigsize=1;
%Simulate the model
data = cvsim(testObj);
%Set the block handle
blk_handle = get_param([mdl, '/Switch'], 'Handle');
%Get signal size data
[minVal, maxVal, allocVal] = sigsizeinfo(data, blk_handle);

Alternatives

Use the coverage settings to collect signal size coverage for a model:

Open the model for which you want to collect signal size coverage.
In the Simulink Editor, select Model Settings on the Modeling tab.
On the Coverage pane of the Configuration Parameters dialog box, select Enable coverage analysis.
Under Coverage metrics, select Signal Size.
Click OK to close the Configuration Parameters dialog box and save your changes.
Simulate the model by clicking the Run button and review the results.
