ok, I’m backing up and decided to start with something easier to get familiar with magic, now I’m trying to make this inv into a tie by moving that square of li to position shown and removing the input (amazing how close these gates are)…. I’m watching some tutorials, but seems hard to proceed without middle button…tips appreciated. Ahá! just discovered ^D and p 🙂
Making progress here, not sure how to go about selecting objects now, ie: keep deleting all inside my selected boxes, not sure how to select pins, like delete A
ahá! :erase lables
next challenge move that Y label up…
uh, some garbage remains

ok…kind of stuck now without the spice models

@20Mhz: Use the menu "Edit->Text..." to create the label, so you can set the size (in microns). Also you can just click the checkbox to make it a port.

ok, I may have over compensated. There is no layer selection on that menu though…
t
The layer assignment is automatic unless you uncheck the "default" button, in which case you can select the layer to use. If the label covers multiple materials like the one shown, you probably also want to set the "sticky" flag, which will force the label to always be on the layer indicated (otherwise magic may get confused by the multiple layers).
