Within the S32G platform, there are standard packages (no additional cost) and premium packages. In the S32G2 site it is explained which packages are "standard" and which are "premium" (shown in the "Software Enablement" section).
The Real-Time Drivers (RTD) is one of several packages which supports both AUTOSAR and non-AUTOSAR applications.
