Requirements in block comments

Description

Specify whether to include requirement descriptions assigned to Simulink^® blocks in generated code as comments.

Category: Code Generation > Comments

Settings

Default: Off

On

Inserts the requirement descriptions that you assign to Simulink blocks into the generated code as comments. The code generator includes the requirement descriptions in the generated code in the following locations.

Model Element	Requirement Description Location
Model	In the main header file `model.h`
Nonvirtual subsystems	At the call site for the subsystem
Virtual subsystems	At the call site of the closest nonvirtual parent subsystem. If a virtual subsystem does not have a nonvirtual parent, requirement descriptions are located in the main header file for the model, `model.h`.
Nonsubsystem blocks	In the generated code for the block

For information on code generator treatment of strings that are unrepresented in the character set encoding for the model, see Internationalization and Code Generation.

Off

Suppresses the generation of comments for block requirement descriptions.

Dependency

This parameter only appears for ERT-based targets.
This parameter requires Embedded Coder^® and Simulink Requirements™ licenses when generating code.

Tips

If you use an external .slmx file to store your requirement links, to avoid stale comments in generated code, before code generation, you must save any change in your requirement links.
