sigrangeinfo - Display signal range coverage information for model object

Syntax

[min, max] = sigrangeinfo(cvdo, object) [min, max] = sigrangeinfo(cvdo, object, portID)

Description

[min, max] = sigrangeinfo(cvdo, object) returns the minimum and maximum signal values output by the model component object within the cvdata object cvdo. See Specifying a Model Object for more information about the object argument. If object outputs a vector, min and max are also vectors.

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

Specifying a Model Object

The object argument specifies an object in the Simulink model or Stateflow^® diagram that received decision 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 block and the ID of an object contained in that chart
{BlockPath, sfObj}	Cell array with the path to a Stateflow block and a Stateflow object API handle contained in that chart
[BlockHandle, sfID]	Array with a Stateflow block handle and the ID of an object contained in that chart

Example

The following commands open the slvnvdemo_cv_small_controller demo model, create the test specification object testObj, enable signal range coverage for testObj, and execute testObj.

mdl = 'slvnvdemo_cv_small_controller';
open_system(mdl)
testObj = cvtest(mdl)
testObj.settings.sigrange = 1;
data = cvsim(testObj)

Afterward, issue the following commands to retrieve the signal range for the Product block.

blk_handle = get_param([mdl, '/Product'], 'Handle');
[minVal, maxVal] = sigrangeinfo(data, blk_handle)
