By default autosar releases a Ecu description paramdef while gives a default implementation of Autosar BSW. Where we metmodel define all the BSW module seperately. This is an auxiliary document, you should always base your development on SWS. M0, M1, M2 are different metalevels, where enities in M0 are meyamodel in terms of M1 entities and so on.

For this you have to understand what is a metamodel. It contains the UML model for Autosar.


And this Metamodel becomes the model for the next metamodel below it. Author and commenters Vinay Kansal. The BSW part of the Autosar model wutosar generic in nature to support any vender specific data. The paramdef model can always be realised in term of Autosar model as it is very generic.

Could you please elabrote on that. So, the only chance is doing it by hand, or using Artop Demonstrator as a facilitator. In addition to that, since R3. Now a model and its metamodel are to different levels.

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.

As the Autosar give the end user a flexibility to add any new BSW containers or parameter. For the BSW part of the Autosar model. The paramdef file has a more strict rules as the name of the BSW containers are specifically defined in it alond with its parameter.

As of now, I do not know any tools which are supporting BSW module description. The Autosar Model is a combination of all the Autosar Template. The Ecuparamdef file is one such paramdef file released by Autosar.


Its a generic kind of implementation in the model. Now i can open this model. This means the paramdef file is realised autossar of Autosar Model. To summarize the stuff Autosar metamodel is the superset and the Ecuparamdef is a subset of it. Does it contain Architecture of all BSWs?

I am not sure why you got a feeling that autossar Autosar model is incomplete. Only visible to XING members. A metamodel is a precise defination of the constructs and rules.

Thomas Zurawka Premium Moderator. Hence you can say from the most abstract model we create another metamodel where the and rules are more autosad defined.
