AUTOSAR ARXML FILE

• .xml file:- Database that stores data in the form of tags and texts.
• .arxml file:- AUTOSAR .xml Database of AUTOSAR Configuration parameter.

Types of arxml file present are:-

1. System Configuration
2. ECU Extract
3. ECU Configuration
4. Software Description
5. BSW Module Description.

1. System Configuration File:-

• Information of Multiple ECU's
• Messages, Signals sent and received by the ECU
• Ports, Interfaces of software component across ECU's
• System configuration is basically represented as a network of a ECU, so the system configuration of a file contains the information that means the signals, messages or components present in each ECU are represented in the system configuration.

2. ECU Extract:-

• Message and signals sent or received by a single ECU.
• SWC details like Port and Interfaces of a single ECU.
• We can say ECU extract is the subset of the system configuration.

3. ECU Configuration:-

• Contain configuration parameter of BSW modules as specified in AUTOSAR SWS.
• Module specific configuration.
• User can edit the configuration and generate the module as per AUTOSAR methodologies.
• AUTOSAR tool chain takes the ECU extract as an input imports it to the tool chain and provide the configuration, ECU Configuration as the output.
• We have seen ECU Configuration like COM, PduR, CanIf etc. so these are the module specific configuration that are part of the ECU Configuration.

4. SWC Description:-

• SWC details separates from ECU extract.
• SWC details of specific SWC.
• No message and signals.

5. BSW Module Description:-

• BSW module decryption is provided for every AUTOSAR BSW module.
• This basically contains the configuration of the schedulable entities of a particular BSW module.

Differences:-

System Configuration, ECU Extract, SWC Description, BSWMD contains configuration parameters like:-

• System Signals, Isignals, Frame, Isignal, IPdu.
• Atomic Software Component, Service Software Component, Internal Behaviour, P-port, R-port.
• Runnable entity, Timing event, Data Received Event.
• Sender Receiver Interface, Client Server Interface, Mode Switch Interface.

ECU Configuration:-

• Configuration of BSW module:- COM, PduR, CanIf, EcuM, DCM,Nvm etc.
• ComSignal, ComSignalGroup, PduRouting path, EcuM General, CanIfRxPdu, Dcm, Nvm Block Description.
