Detect non-reused custom storage classes

Description

Select the diagnostic action to take when your model contains a Reusable custom storage class that the code generator cannot reuse with other uses of the same Reusable custom storage class. The default behavior of the parameter settings varies with the presence of Reusable custom storage classes and referenced models. If the code generator cannot change the block execution order to enable reuse or the conditional execution of some blocks is incompatible with reuse, the code generator might not implement the reuse specification. The generated code will likely contain additional global variables.

For example, in this model, the code generator cannot reuse the variable Y to hold the outputs of In2, Gain, and Gain2 because Gain executes before Gain2. The generated code contains an extra variable to hold the Gain output. The red numbers to the top right of the blocks indicate the execution order.

Settings

Default: warning

none: Simulink^® software takes no action.
warning: Simulink software displays a warning.
error: Simulink software terminates the simulation and displays an error message.

When there are Reusable custom storage classes and referenced models present, the parameter settings are:

None: Simulink software generates a message for you to set the parameter to Error.
Warning: Simulink software generates a message for you to set the parameter to Error
Error: If Reusable custom storage classes can be combined Simulink software generates code. If not, it generates an error.

Tip

If you do not want the generated code to contain additional global variables because of a Reusable custom storage class specification that the code generator cannot honor, set this parameter to error. Remove the Reusable custom storage classes from the signal lines in the error message.
