I’m using the “Single Track Length Tuning” tool and in the tool settings, I was wondering how can I enable access for the drop-down menu for “Tune from:”, “Tune to:” and “Constraint” fields?
If I guess right, these options are to select a net to tune from/to which I would rather use instead of manually entering a Target length.
Where is the “Constraint:” drop-down list controlled from? What does it do?
I don’t know. I see the “Tune from” and “Tune to” pulldowns are always empty in KiCad 5.1.5 when I try a few nets on a few boards. I would expect that you can choose the nodes of a net to tune each individual connection within a net, but I haven’t used this feature before so maybe I’m doing something wrong.
