Conduit roles

Hello Everyone,

I hope all you are doing great!

My question is: I have one component with a conduit which has 3 signals with 3 distinct roles:

component1:

conduit1 - Conduit
Name Role Width Direction Description
c1_s1 enable 1 Output no description
c1_s2 valid 1 Output no description
c1_s3 data 32 Output no description

And I have another component with 2 conduits but matching roles to the other component's conduit roles' :

component2:

conduit1 - Conduit
Name Role Width Direction Description
c2_s1 valid 1 Input no description


conduit2 - Conduit
Name Role Width Direction Description
c2_s2 data 32 Input

no description

Now can I connect those two latter conduits to the first conduit and hope Qsys will automatically recognize and connect the lines based on roles?

sthg like this:

add_connection compnent1.conduit1 component2.conduit1
add_connection component1.conduit1 component2.conduit2

what I would like to have in the end is have the signals connected:

c1_s2 connected to c2_s1

c1_s3 connected to c2_s2

(c1_s1 no connection.)

Can I do it in this way?

If not, what would be the way to achieve this connectivity in the end given such conduit and signal arrangement?

Best Regards,

Ömer.

    Hi @omerc

    I don't see any problem for now.

    Do make sure that to connect two conduit interfaces inside Platform Designer( formerly called qsys), the following conditions must be met:
    • The interfaces must match exactly with the same signal roles and widths.
    • The interfaces must be the opposite directions.
    • Clocked conduit connections must have matching associatedClocks on each of their endpoint interfaces.

    Reference:
