Create Protected Model
This figure illustrates the various options in the Create Protected Model dialog box.
Create Protected Model: Overview
Create a protected model (.slxp) that allows read-only view, simulation, and code generation of the model with optional password protection.
To open the Create Protected Model dialog box, right-click the model block that references the model for which you want to generate protected model code. From the context menu, select Subsystem & Model Reference > Create Protected Model for Selected Model Block.

Open read-only view of model
Share a view-only version of your protected model with optional password protection. View-only version includes the contents and block parameters of the model.
Settings
Default: Off
On Share a Web view of the protected model. For password protection, create and verify a password with a minimum of four characters.
OffDo not share a Web view of the protected model.

Simulate
Enable user to simulate a protected model with optional password-protection. Selecting Simulate:
Enables protected model Simulation Report.
Sets Mode to Accelerator. You can run normal, accelerator, and rapid accelerator mode simulations.
Displays only binaries and headers.
Enables code obfuscation.
Settings
Default: On
- On
User can simulate the protected model. For password protection, create and verify a password with a minimum of four characters.
- Off
User cannot simulate the protected model.

Use generated code
Allows user to generate code for the protected model with optional password protection. Selecting Use generated code:
Enables Simulation Report and Code Generation Report for the protected model.
Enables code generation.
Enables support for simulation.
Settings
Default: Off
- On
User can generate code for the protected model. For password protection, create and verify a password with a minimum of four characters.
- Off
User cannot generate code for the protected model.
Dependencies
To generate code, you must also select the Simulate check box.
This parameter enables Code interface and Content type.

Code interface
Specify the interface for the generated code.
Settings
Default:
Model reference
Model referenceSpecifies the model reference interface, which allows use of the protected model within a model reference hierarchy. Users of the protected model can generate code from a parent model that contains the protected model. In addition, users can run Model block software-in-the-loop (SIL) or processor-in-the-loop (PIL) simulations to verify code.
Top modelSpecifies the standalone interface. Users of the protected model can run Model block SIL or PIL simulations to verify the protected model code.
Dependencies
Requires an Embedded Coder® license
This parameter is enabled if you:
Specify an ERT (
ert.tlc) system target file.Select the Use generated code check box.

Content type
Select the appearance of the generated code.
Settings
Default:
Obfuscated source code
BinariesIncludes only compiled binaries for the generated code.
Obfuscated source codeIncludes obfuscated source code.
Readable source codeIncludes readable source code and readable code comments.
The options Obfuscated source code and
Readable source code by default include only the
minimal header files required to build the code with the chosen build settings.
These options correspond to using the Simulink.ModelReference.protect with
the 'OutputFormat' option set to
'MinimalCode'. To include header files found on the
include path in the protected model, use the Simulink.ModelReference.protect
function and set the 'OutputFormat' option to
'AllReferencedHeaders'.
The Binaries option corresponds to using the
Simulink.ModelReference.protect
function with the 'OutputFormat' option set to
'CompiledBinaries'.
Dependencies
This parameter is enabled by selecting the Use generated code check box.

Use generated HDL code
Allows user to generate HDL code for the protected model with optional password protection. Selecting Use generated HDL code:
Enables Simulation Report and HDL Code Generation Report for the protected model.
Enables support for HDL code generation.
Enables support for simulation.
Settings
Default: Off
- On
User can generate HDL code for the protected model. For password protection, create and verify a password with a minimum of eight characters.
- Off
User can simulate but cannot generate HDL code for the protected model.
Dependencies
To generate HDL code, you must also select the Simulate check box.

Destination folder
Specify the path of the folder to contain the protected model.
Settings
Default: Current working folder
Dependencies
A model that you protect must be available on the MATLAB® path.

Contents
Option to package supporting files, including a harness model, with the protected model in a project archive. The type and number of supporting files depends on the model being protected. Examples of supporting files are a MAT-file with base workspace definitions and a data dictionary pruned to relevant definitions. The supporting files are not protected.
Note
Before sharing the project, check whether the project contains the necessary supporting files. If supporting files are missing, simulating or generating code for the related harness model can help identify them. Add the missing dependencies to the project and update the harness model as needed.
Settings
Default:
Protected model (.slxp) and dependencies in a
project
Protected model (.slxp) and dependencies in a projectCreate a project archive that contains the protected model, its dependencies, and its harness model. The supporting files are not protected. The project archive is a single file that allows for easy sharing.
Protected model (.slxp) onlyCreate only the protected model. If the protected model has dependencies, you must share them separately. Similarly, if you create a harness model for the protected model, you must share the harness model separately.

Create harness model for protected model
Create a harness model for the protected model. The harness model provides an isolated environment for the protected model, which is referenced by a Model block.
Settings
Default: Off
- On
Create a harness model for the protected model.
- Off
Do not create a harness model for the protected model.
Dependencies
To clear the check box for this parameter, set Contents
to Protected model (.slxp) only.

Settings
Default:
