Enable local block outputs

Description

Specify whether block signals are declared locally or globally.

Category: Optimization

Settings

Default: On

On

Block signals are declared locally in functions.

Off

Block signals are declared globally.

Tips

• If it is not possible to declare an output as a local variable, the generated code declares the output as a global variable.

• If you are constrained by limited stack space, you can turn Enable local block outputs off and still benefit from memory reuse.

Dependencies

• This parameter requires a Simulink^® Coder™ license.

• This parameter is enabled by Signal storage reuse.
