"SIMULINKGlobal" Storage Class is not available

Hello,

I am writing to ask for assistance with an issue I am facing in Simulink. I am trying to define tunable parameters for code generation using a Data Dictionary, but the SIMULINKGlobal storage class is not available as an option.

I have already performed the following configuration and troubleshooting steps based on the documentation, but the option remains unavailable:

• System Target File: I have confirmed that the target file is set to ert.tlc in Configuration Parameters > Code Generation.
• Embedded Coder License: I have confirmed via the ver command that an active Embedded Coder license is installed and available.
• Code Interface Packaging: I have set this to Reusable function in Configuration Parameters > Code Generation > Interface.
• Root I/O Passing: I have also set Pass root-level I/O as to Part of model data structure.

The SIMULINKGlobal option is missing in all contexts, including the dropdown list in Code Mappings > Data Defaults for "Model parameters" and in the Code Generation tab of an individual Simulink.Parameter object within a Data Dictionary. I have tried several alternatives like ExportedGlobal, but I would like to use the recommended SIMULINKGlobal class for creating a tunable parameter structure.

My system configuration is:

• MATLAB Version: R2024b
• Operating System: Windows 11
• Relevant Toolboxes: Simulink, Embedded Coder

Could you please advise why the SIMULINKGlobal storage class might not be appearing despite these settings being correct? Is this a known issue, or is there another configuration step I might be missing?

Thank you for your time and assistance.

Best regards,

Hi @Ogulcan,

"SimulinkGlobal" storage class has been renamed to "Model Default" since R2018a.

You can refer to the below MATLAB answer provided by the MathWorks Support Team for more details:

I hope this information is helpful to you.
