Technical frame

AUTOSAR Classic Platform: AUTOSAR Classic separates Application, Runtime Environment (RTE) and Basic Software (BSW) at the highest level. The page also includes a worked example and measurement sequence.

The technical values here expose the standard, protocol or physical relationship directly; model-specific service values are linked through the matching model/variant dossier.

The goal is not only to define the term but to let the reader calculate and interpret what the data means in a scan, scope or physical test.

Concrete technical facts

  • AUTOSAR Classic separates Application, Runtime Environment (RTE) and Basic Software (BSW) at the highest level.
  • The RTE abstracts application software components from infrastructure/BSW.
  • BSW includes layers such as Services, ECU Abstraction and Microcontroller Abstraction, with Complex Drivers for special access.
  • The Virtual Functional Bus (VFB) abstracts application communication from final ECU deployment during development.
  • Runnable/event, port/interface and signal/PDU mapping errors can create integration faults without an algorithm being wrong.
  • BSW modules such as DEM, DCM, COM and NvM have different responsibilities for diagnostics, communication and persistent data.

Worked example

  • Layer example: if a sensor value is correct on CAN but does not reach the SWC port, investigate COM→RTE mapping rather than the physical CAN bus.

Measurement and verification sequence

  • Verify signal/PDU mapping against network description.
  • Trace RTE port value and runnable event.
  • Check DEM event to DCM DTC mapping.
  • Compare NvM read/write status with application state.

Fault-separation logic

  • Is a valid command present and are power/ground/network healthy?
  • Does feedback follow the command?
  • Does an independent physical measurement confirm the output?
  • Is the fault limited to a specific temperature/load/speed condition?
  • Does the result remain stable when the original condition is repeated after repair?
