.arxml — AUTOSAR Exchange Format
AUTOSAR Consortium · 2002
ARXML is an XML standard for defining automotive ECU software architecture and configuration.
Key Features
- XML-based structured data format
- Standardized for automotive ECU software description
- Facilitates tool and supplier interoperability
- Defines software components, interfaces, and configurations
Best For
- Standardized automotive software architecture definition
- Interoperability between AUTOSAR-compliant tools
- Configuration and integration of ECU software
- Exchange of design data among automotive suppliers
Less Ideal For
- General-purpose text editing or document creation
- Storing binary data like images or videos
- End-user application configuration or settings
- Web development or front-end design
Common Use Cases
- Defining and exchanging ECU software component specifications
- Configuring communication networks within vehicles (e.g., CAN, LIN)
- Managing software integration between different development tools
- Documenting hardware-software interfaces for automotive systems
How to Open It
- Open with any text editor (e.g., Notepad, VS Code, Sublime Text) for viewing or basic editing.
- Use AUTOSAR-specific modeling and configuration tools (e.g., Vector CANoe/CANalyzer, ETAS ISOLAR-A/B) for full functionality.
- XML editors can parse and validate the structure, providing syntax highlighting and error checking.
What is a .arxml file?
ARXML is an XML-based format used for describing the software architecture of automotive electronic control units (ECUs) within the AUTOSAR standard. It defines the configuration, interfaces, and communication aspects of ECU software components. This structured data facilitates the exchange of design information between different tools and suppliers in the automotive industry. ARXML files are primarily used for configuration and integration, enabling a standardized approach to complex automotive software development.

Common Problems with .arxml Files
Frequently Asked Questions
ARXML files are used to define and exchange the software architecture and configuration of automotive Electronic Control Units (ECUs) within the AUTOSAR standard.
Yes, ARXML files are plain text XML documents and can be read and edited with standard text editors, though specialized tools are recommended for complex tasks.
No, ARXML is specifically designed for the automotive domain and the AUTOSAR standard; it is not intended for general programming tasks.
Technical Details
ARXML files are plain text XML documents, adhering to a specific schema defined by the AUTOSAR consortium. They are not compressed or encoded using specific codecs, as their primary function is data exchange and configuration representation. The structure uses nested XML tags to represent various elements of automotive software, such as modules, ports, and communication matrices.
