cvtest

Create model coverage test specification object

Syntax

cvto = cvtest(root)
cvto = cvtest(root, label)
cvto = cvtest(root, label, setupcmd)

Description

The cvtest command creates a test specification object, that you simulate with the cvsim command.

cvto = cvtest(root) creates a test object with the handle cvto. root is the name of, or a handle to, a Simulink^® model or a subsystem of a model. Only the specified model or subsystem and its descendants are subject to model coverage testing.

cvto = cvtest(root, label) creates a test object with the label label, which is used for reporting results.

cvto = cvtest(root, label, setupcmd) creates a test object with the setup command setupcmd and labels it with label. The setup command is executed in the base MATLAB^® workspace just prior to running the instrumented simulation. This command is useful for loading data prior to a test.

A test object has the following structure.

Field	Description
`id`	Read-only internal data-dictionary ID
`modelcov`	Read-only internal data-dictionary ID
`rootPath`	Name of the system or subsystem instrumented for analysis
`label`	String used when reporting results
`setupCmd`	Command executed in the base workspace just prior to simulation
`settings.condition`	Set to 1 if condition coverage is desired
`settings.decision`	Set to 1 if decision coverage is desired
`settings.mcdc`	Set to 1 if MC/DC coverage is desired
`settings.sigrange`	Set to 1 if signal range coverage is desired
`settings.tableExec`	Set to 1 if lookup table coverage is desired
`modelRefSettings.enable`	String specifying one of the following values: `Off` — Disables coverage for all referenced models `all` — Enables coverage for all referenced models `filtered` — Enables coverage only for referenced models not listed in the `excludedModels` subfield
`modelRefSettings.excludeTopModel`	Set to 1 if excluding coverage for the top model is desired
`modelRefSettings.excludedModels`	String specifying a comma-separated list of referenced models for which coverage is disabled
