RE: [taste-users] TASTE Simulink Bus structure

[<Michael.Dumke@xxxxxx>]

Hi Joaquim,

thanks for the fast answer.

I have not thought about just using the bus selector, I think this solution will suffice.

My problem is just for "aesthetic" reasons, and I was wondering if I could change the ASN.1 in such a way that only the vectors are to be seen in Simulink. If I use the bus selector to just get out the vectors, both are (of course) named "<element_data>".

Thank you very much,

Michael

Dear Michael, 

Imagine that you have a ASN.1 definition similar to the following: 

MyType ::= REAL (-10.0..10.0)
MyArrayA ::= SEQUENCE OF (SIZE(1..3)) OF MyType MyArrayB ::= SEQUENCE OF (SIZE(1..3)) OF MyType MyInput ::= SEQUENCE{ 
        MyArrayA, 
        MyArrayB
} 

This will generate a input Bus in Simulink with 2 signals myarraya and myarrayb, each of these signals has two fields: element_data and length. Then you can use the Selector Block to extract the array elements giving the indexes[1 2 3] from Index Vector. 

I don't know if this addresses your question, but to start it is very important to be sure that your ASN.1 definition is really representing the data types in the way you want. 

Best regards,

Good Morning,

I have a question concerning the interface between TASTE and a Simulink function.
I want to generate a Simulink skeleton that consists of vectors within a bus.
Let's say Input A is a Bus with two vectors a and b with each 3 elements.
At the moment if I build up such a system a and b will be generated as again busses that have each a bus element ("element_data") of size 3.

Is it somehow possible to generate a "single bus structure" and not this "double bus structure" where a and b are just vectors?
I tried using "sequence of" and "set of" but both result in the same Simulink skeleton.

If somebody has an idea I would be very grateful,

Michael Dumke
