Hi Nicky,

In R2020a and earlier, Simulink Real-Time uses a 32-bit real-time OS (RTOS) on the target machine. The maximum quantity of RAM that can be used by your real-time application on the target is therefore 4GB. Extra RAM of the target can be addressed as ERAM for data logging for example, see here.

Starting from R2020b, Simulink Real-Time is based on a 64-bit RTOS, and that limitation is lifted.

Best,

Dimitri
