slwebview_cov

R2026b

Export Simulink models to web views with coverage

Syntax

filename = slwebview_cov(sysname)

filename = slwebview_cov(sysname,Name=Value)

Description

filename = slwebview_cov(sysname) exports the system sysname and its children to a web page filename with contextual coverage information for the system displayed on a separate panel of the layered model structure Web view.

filename = slwebview_cov(sysname,Name=Value) uses additional options specified by one or more name-value arguments.

Note

You must have a Simulink^® Report Generator™ license to use slwebview_cov.

Examples

Export Layers

Export all the layers (including libraries and masks) from the system gcs to the file filename

filename = slwebview_cov(gcs,LookUnderMasks="all",FollowLinks="on")

Input Arguments

sysname — System to export to web view file

character vector | string scalar | handle

System to export to the web view file, specified as a character vector or string scalar that contains the path to the system or a handle to a subsystem, block diagram, chart, or subchart. By default, the function also exports the child systems of the sysname system. Use the SearchScope name-value argument to specify which other systems to export relative to sysname.

Example: "sysname"

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: slwebview_cov(gcs,SearchScope="CurrentAndBelow",LookUnderMasks="all",FollowLinks="on")

Tips

A web view is an interactive rendition of a model that you can view in a web browser. You can navigate a web view hierarchically to examine specific subsystems and to see properties of blocks and signals.

You can use web views to share models with people who do not have Simulink installed.

Web views require a web browser that supports Scalable Vector Graphics (SVG).

Version History

Introduced in R2015a

R2026b: Monitor web view export progress

Use the Verbose, Verbosity, and ShowProgressBar name-value arguments to monitor or suppress progress information during web view exports. By default, the function displays normal-level progress messages. To silence all messages, set Verbose to false.

R2026b: Control which UI elements appear in an exported web view

Use the IncludeViewAllTab and IncludePropertyInspector name-value arguments to specify whether to include the View All tab and the Property Inspector in the generated web view.

R2026b: Export a subsystem as a standalone web view

Use the UseCurrentSystemAsRoot name-value argument to make the specified subsystem the top-level root in the generated web view.

R2026b: Export variants with startup activation time

Set the IncludeVariantSubsystems name-value argument to "ActivePlusCode" to export variants that have the "startup" activation time.

R2026a: Option to specify variant subsystems in web view

When generating a model web view, choose which variant subsystems to include by using the propertyIncludeVariantSubsystems. The default behavior is to include all variant subsystems in the model web view.

R2025a: Display parameters for masked Stateflow subcharts in web view

Web views now display mask parameters for masked Stateflow subcharts.

R2024b: Option to exclude referenced subsystems in web view

When generating a model web view, choose whether or not to include referenced subsystems by using the propertyFollowSubsystemReference. The default behavior is to include referenced subsystems in the model web view.
