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
