How do I change a signal name that doesn't have a wire

izucker

Hi,

I have a "noConn" (from basic lib) connected directly to an Instance terminal.

There is no wire in between the two objects, meaning that it won't take a "label" for changing the net name.

How can I rename that (internal) signal name in this case? 

Thanks,

Itay

    Hi Itay,

    There's always a first time!

    The challenge is, how would you attach a label to the thing that needs to be named when there is nothing physical to attach to? Possibly you could attach the label to the noConn component, but this would be a bit of a special case. What about the situation where you have two series connected resistors which have overlapping pins - how would you name the net then? You can't attach a label to an instance, because it wouldn't know which pin you wanted it to belong to.

    To some extent, there have to be some semantics associated with how the physical drawing is converted into logical connectivity, and so some rules/limitations apply.

    So if you can think of a good/usable way of naming the net, I can propose it - I just can't think of a way it would be done...

    Regards,

    Andrew.
