Matthias,
In the technology file, could it be possible to associate a layer to another to attach node name to a metal layer ?
When highlighting a net, it would be nice to have its name.
At the same time, if 2 or more names are given to a single net, it would a very nice feature for debug.
... it would be a nice step towards LVS :)
BRgds,
Laurent

Hi Laurent,
I'm not sure if I understand. Labels from a specific layer are taken to be the net name. Do you mean that it should be possible to specify a different layer as source for these labels?
Matthias
- Metal1 is the layer 15/0 (a layer for routing polygons or paths)
- Metal1 text is the layer 15/1 (a different layer for names)
So, if we can attach / connect those 2 layers and if the 'Trace net' can attach the label detect in one of those layers to the net, then we could have the name of the highlighted net.
If several names are detected/attached to the highlighted net, then, a warning or a message can be very useful to debug a layout.
Thanks, BRgds,
Laurent
... or a warning if 2 or more names are given :(

Hi Laurent,
I tried the following:
with this layer connectivity definition:
I can extract the labels on 15/1 and 17/1 and the net is named according to the label.
So I think this is possible already. The only issue I see is the case of label conflicts: if you have more than one label on the net, KLayout will pick one of them (I think the first one it encounters).

Matthias
Beside, it would be nice to have the complete list of labels conflicting : a very nice feature for layout debug :)

Laurent
