Hi @Kazarian,
1. The RTD package includes some example modules for each driver. You can find them under your installation (by default: C:\NXP\SW32K3_S32M27x_RTD_R21-11_5.0.0). You can select "Import > General > Existing Projects into Workspace" and with the "Select root directory", add the path to the example you need, for example: "C:\NXP\SW32K3_S32M27x_RTD_R21-11_5.0.0\eclipse\plugins\Adc_TS_T40D34M50I0R0\examples\EBT\S32K3XX\Adc_example_S32K344"

2. Tresos does support RTE generation and SWC integration, however, the RTE module released in the RTD package for S32K3 devices is only a support stub, it does not support configuration. This is only for testing purpose from our side. You will need to contact a third-party provider, such as Elektrobit(EB), Vector, etc, for a compatible package.
For a full-on description on RTE & SWC configuration, I suggest contacting Elektrobit, as they have some training materials regarding AUTOSAR workflow: EB tresos Studio demonstrator – Elektrobit. They cover general topics such as configuring ECUs, including features (Importer, Exporters, System Description Editors, etc.), functionality (SWC to ECU mapping, generating ECU extract, derive ECU configuration, etc.), among other things.
We do not provide any specific tools for SWC & RTE compatibility.
Best regards,
Julián
