Hello,
You cannot use Simulink (MBDT) together with S32DS to generate directly AUTOSAR‑compliant code.
Please see below link:

Or is it mandatory to use Simulink (MBDT) with EB Tresos only?
EB tresos is NOT mandatory for using MBDT.
Besides, does the RTD of S32K3 comply with AUTOSAR specification?
No — the S32K3 RTD is not fully AUTOSAR-compliant by itself. RTD supports both AUTOSAR and non-AUTOSAR applications.
To be AUTOSAR-compliant ECU software, you need the full stack:
Application (SWC), RTE, BSW (Services, ECU abstraction), MCAL
