Hi, to achieve the desired code generation with a virtual bus, you can use structure padding and code replacement techniques. Here's how you can implement it:
1. Create a 'Simulink.Bus' object in your Simulink model to represent the virtual bus. Add the necessary signals and sub-buses as elements of the virtual bus.
2. In the Data Dictionary, create a structure type definition for each sub-bus (`SubBus1_T`, `SubBus2_T`, etc.) and define the variables inside each sub-bus.
3. Create a structure type definition for the virtual bus (`ExtY_ModelName_T`) and include the sub-bus types as elements of the virtual bus type.
4. In the Code Mappings editor, set the storage class of the virtual bus output (`ExtY`) to `struct` and specify the structure type as `ExtY_ModelName_T`. This will ensure that the generated code uses the structure type for the virtual bus.
5. In the Code Mappings editor, define code replacements to rename the individual variables inside the virtual bus to match the desired naming convention. For example, replace `ExtY_SubBus1_Var1` with `SubBus1.SubBus1_Var1`, and so on.
By following these steps, the generated code should reflect the desired structure and variable names for the virtual bus.
