In our Simulink model mapped to AUTOSAR I could mapped each Function to the specific swAddrMethod and I get the code I expected:
/* SwAddrMethod QM_PERIODICAL_CODE for Runnable */
#define MySWComponent_START_SEC_QM_PERIODICAL_CODE
#include "MySWComponent_MemMap.h"
void MyFunc(void)
{
/*****/
}
#define MySWComponent_STOP_SEC_QM_PERIODICAL_CODE
#include "MySWComponent_MemMap.h"
I also create a swAddrMethod = QM_VAR_INIT (sectionType = var)
but how can I map the global variable automatically created after code generation in a specific memory section?
For example after code generation I found the following global struct
/* PublicStructure Variables for Internal Data */
ARID_DEF_CtApOutputSignal_T CtApOutputSignal_ARID_DEF;
and I would like to get something like:
/* SwAddrMethod QM_RTE_VAR_INIT for Internal Data */
#define MySWComponent_START_SEC_QM_VAR_INIT
#include "MySWComponent_MemMap.h"
ARID_DEF_CtApOutputSignal_T CtApOutputSignal_ARID_DEF;
#define MySWComponent_STOP_SEC_QM_VAR_INIT
#include "MySWComponent_MemMap.h"

Hi Elisa,
Enabling the 'Generate separate internal data per entry-point function' in the model's config settings allows for assigning memory sections to internal data:
https://www.mathworks.com/help/ecoder/ref/generateseparateinternaldataperentrypointfunction.html
This separation results in distinct structures for the internal data of each runnable. By specifying the SwAddrMethod for internal data of individual runnables as needed, you can generate the desired pragmas/memory sections for internal data.
Please see below screenshots for detailed steps:
Hope this helps!

Hello, I have the same issue. I tryed the described configurations in Code generation settings for Interface. But I get still the same result.
All functions and variables are mapped correctlictly. But the only chart inside of a subsystem is defined as a publicstructure variable for internal data in the generated c-code, which is not mapped (memory section) at all.
Is there any specific configuration parameter for stateflow logics in code generation section?
