ETAS RTA-RTE (runtime environment) provides the runtime environments (RTE) for AUTOSAR-compliant ECU software. It supports the latest versions of the relevant AUTOSAR, OSEK*/VDX, ISO 26262, and MISRA C* standards.

Generator for AUTOSAR runtime environments

RTA-RTE include the following features:

  • Communication infrastructure for all application software components
  • Real-time scheduling of software components
  • Interface between application software components and basic software modules


  • ISO 26262 (ASIL-D)-certified AUTOSAR run-time environment
  • Easy integration into development environments via command-line generation interface
  • Optimization of runtime environment to exactly match requirements of application
  • Compatibility with all types of compiler and target hardware means it can be used by many different ECU platforms
  • Easy debugging via virtual function bus (VFB) tracing
  • Variants available that support AUTOSAR Contract Phase or offer the full range of functions for generating code


  • Generation of runtime environments in compliance with AUTOSAR releases 4.x and 3.x
  • Numerous options for configuring the generated runtime environment
  • Checking of XML input data for accuracy and consistency
  • Output of operating system configuration in order to integrate runtime environment with operating system
  • Support of source or object code from C and C++ software components


* OSEK (which stands for “Offene Systeme und deren Schnittstellen für die Elektronik in Kraftfahrzeugen” or "Open Systems and their Interfaces for Electronics in Motor Vehicles" in English) is a predecessor standard of AUTOSAR.

* MISRA C (Motor Industry Software Reliability Association) is a C programming standard, which defines a language subset of the programming language C.
