I am trying to generate a C++ code for my Simulink model. Everything works fine, but the problem I have is that the struct name that is generated is not consistent, and I am not sure what the problem is, although I have not changed anything in the Embedded Coder Configurations.

For example:

Before the struct was generated as follows:

struct ExtY_moduleName_T

Now it's just:

struct ExtY

Or

// Parameters (default storage)
struct P_moduleName_T

Now it's just:

// Parameters (default storage)
struct P

How can I keep this consistent, what causes the _moduleName identifier to be removed ? I checked under Settings -> Code Generation -> Identifiers and this is what I got:

On the left are the expected values and on the right are the new values (without _moduleName), why did it change ?

I'm using Matlab R2023b.

That can be explained by the "$N$R$M_T" on the left and "$N$M" on the right for "Global types". "$R" means root model name. "_T" is explicit suffix.

What do you mean by "expected" and "new". They are two model configurations. They are apparently different or has been changed for naming rules for "Global types".
