AUTOSAR Engineer

✓ Link any model element with AUTOSAR elements (e.g. requirements traceability)
✓ Integration of Enterprise Architect into your AUTOSAR tool chain via ARXML
✓ Modelling of component behavior like runnables, events and inter-runnable variables
✓ AUTOSAR documentation generation




LieberLieber AUTOSAR Engineer is a new product package from LieberLieber for the professional creation of AUTOSAR models using Enterprise Architect by Sparx Systems. This package is based on a UML AUTOSAR profile that allows the creation of models directly in Enterprise Architect in accordance with the AUTOSAR 4 Virtual Function Bus (VFB) specification. The profile provides all necessary AUTOSAR elements like components, interfaces, runnables, etc.

The LieberLieber Modeling Assistants are built in to ensure fast and fluid modeling. These assist modelers by, for example, automating the transfer of setting when model elements are connected, or during the layout of components with port elements. They increase productivity, save time, provide extended layout functionalities and ensure a valid model, because they extend the model validation capabilities of Enterprise Architect with a focus on AUTOSAR modeling.

You can export the data from your AUTOSAR model using the LieberLieber AUTOSAR Connector in the AUTOSAR ARXML format, with which a continuous AUTOSAR tool chain can be configured or the model can be integrated into an existing tool chain.

LieberLieber AUTOSAR Engineer offers the following features:
  • Support for the AUTOSAR 4 VFB modeling standard (component types, interfaces, runables, …) by a UML2 profile
  • Inclusion of further modeling options (e.g. modeling of events to start runnables)
  • Intelligent modeling support from modeling assistants in the background – e.g. name, type and direction are automatically set on a new connected port
  • Enterprise Architect Quick-Linker is supported
  • Mixed modeling with UML and SysML in the same repository is possible and supported
  • ARXML export
The following show two AUTOSAR VFB models created with the help of LieberLieber AUTOSAR Engineer. This example is from the AUTOSAR 4 VFB specification.


The modeling of behavior of component such as runnables, events and inter-runnable variables is supported by LieberLieber AUTOSAR Engineer.



From the AUTOSAR website:

The AUTOSAR standard will serve as a platform upon which future vehicle applications will be implemented and will also serve to minimize the current barriers between functional domains. It will, therefore, be possible to map functions and functional networks to different control nodes in the system, almost independently from the associated hardware.

To achieve the technical goals modularity, scalability, transferability and re-usability of functions, AUTOSAR will provide a common software infrastructure for automotive systems of all vehicle domains based on standardized interfaces for the different layers shown in the top right image. AUTOSAR enables configuration process optimization (e.g. partitioning and resource usage) and where necessary, to allow local optimization if required to meet the runtime requirements of specific devices and hardware constraints.
