Re: [taste-users] TASTE Simulink Bus structure

[joaquim.rosa@xxxxxxx]

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,

Subject:	[taste-users] TASTE Simulink Bus structure

---

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
