The Ecuparamdef file is one such paramdef file released by Autosar. And this Metamodel becomes the model for the next metamodel below it.

Author and commenters Vinay Kansal. So, the only chance is doing it by hand, or using Artop Demonstrator as a facilitator. In addition to that, since R3. This means the paramdef file is realised out of Autosar Model.

For the BSW part of the Autosar model. Now i can open this model. A metamodel is a precise defination of the constructs and rules. To summarize the stuff Autosar metamodel is the superset and the Ecuparamdef is a subset of it.


By default autosar releases a Ecu description paramdef while gives a default implementation of Autosar BSW. The paramdef file has a more strict rules as the name of the BSW containers are specifically defined in it alond with its parameter.

The BSW part of the Autosar model is generic in nature to support any augosar specific data. Only visible to XING members. This is an auxiliary document, you should always base your development on SWS. Now I have another question if its incomplete model then does developer needs to fill it?

As of now you have to build a model out of the paramdef if you want to see the BSW structure. M0, M1, M2 are different metalevels, where enities in M0 are expressed in terms of M1 entities and so on.

Could you metxmodel elabrote on that. It contains the UML model for Autosar. As of now, I do not know any tools which are supporting BSW module description. Hence you can say from the most abstract model we create another metamodel where the and rules are more descriptively defined.


For this you have to understand what is a metamodel.

I am not sure why you got a feeling that the Autosar model is incomplete. Where we don’t define all the BSW module seperately.

Thomas Zurawka Premium Moderator. Does it contain Architecture of all BSWs? As the Autosar give the end user a flexibility to add any new BSW containers or parameter. Its a generic kind of implementation in the model.

The paramdef model can always be realised in term of Autosar model as it is very generic.
