Error On Storage Class

Error using tlc_c The model 'SWC_Main' has a subsystem block 'SWCMainProcs' which contains a block () that has a '_VAR_SWC_VAR_CLEARED_16' storage class registered with it. The storage class is unstructured. Data inside of 'Variant Subsystem' or 'For Each Subsystem' cannot be unstructured.

How to fix this error.

Hello @Annu,

I understand you are facing an error regarding storage class.

The error message you are getting seems to indicate you have a signal or parameter (which becomes _VAR_SWC_VAR_CLEARED_16 during code generation') inside a Variant or For-Each Subsystem that is assigned an unstructured storage class such as “ExportedGlobal” or “ImportedExtern”.

Switching the storage class to a structured type such as Struct or moving the data outside the Variant/For-Each Subsystem should help resolve the issue.

The following documentation link provides more information on choosing storage classes:

Hope this helps!
