The paramdef file has a more strict rules as the name of the BSW containers are specifically defined in it alond with its parameter.

To summarize the stuff Autosar metamodel is the superset and autossar Ecuparamdef is a subset of it. And this Metamodel becomes the model for the next metamodel below it.

This means the paramdef file is realised out of Autosar Model. Hence you can say from the most abstract model we create another metamodel where the and rules are more descriptively defined.


As the Autosar give the end user a flexibility to add any new BSW containers or parameter. Now I have another question if its incomplete model then does developer needs to fill it? This is an auxiliary document, you should always base your development on SWS. But again a end user can add or remove stuff from it. Author and commenters Vinay Kansal.

Does it contain Architecture of all BSWs? The paramdef model can always be realised in term of Autosar model as it is very generic.

Where we don’t define all the BSW module seperately. M0, M1, M2 are different metalevels, where enities in M0 are expressed in terms of M1 entities and so on. Thomas Zurawka Premium Moderator.

, What does it contain. – AUTOSAR | XING

I am not sure why you got a feeling that the Autosar model is incomplete. It contains the UML model for Autosar. The BSW part of the Autosar model is generic in nature to support any vender specific data. For this you have to understand what is a metamodel. Its a generic kind of implementation in the model.


The Autosar Model is a combination of all the Autosar Template. By default autosar releases a Ecu description paramdef while gives a default implementation of Autosar Auotsar.

Only visible to XING members. For the BSW part of the Autosar model.

In addition to that, since R3. A metamodel is a precise defination of the constructs and rules. As of now, I do not know any tools which are supporting BSW module description. The Ecuparamdef file is one such paramdef file released by Autosar. Now i can open this model.

Could you please elabrote on that. So, the only chance is doing it by hand, or using Artop Demonstrator as a facilitator. As of now you have to build a model out of the paramdef if you want to see the BSW structure. Now a model and its metamodel are to different levels.
