IntroductionAramis logo

Aramis is a powerful tool helping developers with architecture, design and implementation of software on ECUs in an AUTOSAR environment. Engineers in the automotive industry can model AUTOSAR objects (stored in a central database) and exchange them (via ARXML files) by using Aramis. Aramis has a similar scope as ADD but is focused on the AUTOSAR methodology.

Advantages

  • Aramis provides convenient abstractions for complex AUTOSAR concepts. This enables end users to efficiently manage AUTOSAR objects on a high level without the need to delve into the details of ARXML. Aramis is not just an XML editor.
  • Aramis is backed by a 3-tier architecture and is optimized for global usage. This allows simultaneous usage by teams distributed across the world.
  • Aramis is based on a central database (single source). This enables reuse of objects in a multi-user environment across multiple projects.
  • Aramis provides extensive consistency checks on the data. Feedback at an early stage reduces further costs in the development process.
  • Users can control Aramis via a convenient graphical user interface. Furthermore, build steps and other tools can invoke Aramis via a command line interface (CLI).
  • Upon request, Aramis can be easily adapted to customer-specific use cases.

Main Features

Architecture

  • Define architecture with the help of “white boxes” (hierarchical structures of SW component types) to faciliate reuse and encapsulation of software components.
  • Guidance of the user by defining “architecture packages”. They reduce the predefined objects available in a composition SW component type. Moreover, they allow to mark certain objects (e.g. application data types) as recommended.
  • Visualization of software architecture, data flow and data access

Modelling

  • Types of objects which can be modelled in Aramis:
    • Composition SW component types
    • Sender receiver interfaces / parameter interfaces / NV data interfaces:
      • Maps
      • Axes
      • Primitives
      • Structs
    • Client server interfaces
    • Mode switch interfaces
    • Trigger interfaces
    • System constants
    • Runnable entities
    • SWC service dependencies with service needs, e.g.:
      • Diagnostic event needs
      • OBD service needs
      • Function inhibition needs
      • Supervised entity needs
      • NV block needs
    •  Consistency needs (multi-core)
    • Sequence needs (VFB timing)
    •  Memory sections
    • NV blocks
    • Application data types
    • Implementation data types
    • Units
    • …
  • Control automotive safety integrity level (ASIL) of composition SW components.
  • It is possible to store the origin of objects (e.g. customer or department).
  • Management of non-volatile data (NV data interfaces, NV blocks and NV block needs)
  • Calibration of data (e.g. define initial values)
  • Sequencing of runnable entities

Checks & Versioning

  • Extensive consistency checks and validations on multiple levels, e.g. individual interfaces, single SW component types as well as their hierarchic relationships
  • Aramis features a version management of data. For example, it is possible to create new versions of existing objects taking over the previous attributes.
  • Management of user rights and object lifecycle (status, responsible user). These mechanisms also control which objects can be edited and reused by which users.
  • Customizable checks of naming conventions (naming rules can be taken from configuration files or from custom databases)

SWCs & ARXML

  • Define SW component types and their contents
  • Export of ARXML files
  • Import of ARXML files and synchronization with existing SW component types in the Aramis database. The synchronization includes a dedicated user interface to interactively solve data conflicts which haven’t already been corrected automatically.
  • Automatic generation of elaborate AUTOSAR structures including
    • Complex data types, e.g. arrays of application data types and their corresponding implementation data types
    • Assembly connectors and delegation connectors
    • NV block component types
    • Sequence needs (VFB timing)
    • Atomic SW component types like application, parameter, complex device driver, etc.
    • Standard service client server interfaces and runnable entities
    • Compu methods

Further Properties

  • The client and the server components of Aramis can be installed via copy deployment. The server component can alternatively be installed as Windows service (recommended).
  • Runs without pre-installed database driver software
  • Doesn’t require additional application server software
  • Supports multiple databases environments (e.g. productive, testing, etc.) which can be configured centrally
  • Aramis includes a command-line tool which can evaluate formulas written in AUTOSAR formula language.
