Hi, Is there a way to place note text in a Cadence allegro PCB layout design? In altium I used to place a lot of text note on mechanical and other layers, now in allegro I cant find a menu option to do that.
You probably know that you can translate part libs from orcad to concept/allegro with transolb.exe. I think there is no similar translator for footprints. maranaza
I suggest creatinga new pad stack just in case any other symbol in your library uses the padstack that you want to edit. allegro has several options to refresh the pad stacks, of which some will refresh ALL pad stacks in the design. This can be a fatal mistake! (Some designers creats different padstacks with same name residing in different li

you don't need any "copy+paste", the idea of "manually change coordinate and references in excel" even worse. :) Capture CIS / allegro has very good "re-use" module support for your design. check the keyword "RE-USE" in the software's help/document, you will done your task quickly in more "professional" way.

In OrCAD or Capture CIS for those components where You wish to do this You add a properties called ROOM. Eg PowerSupply. In allegro You create some room shapes for each group. Then do a quickplace where You set mark in "place by room" (Or something like that). When this is completed You are done.

I don't know allegro, but sometimes I just accept that I am going to get a DRC error with unusual structures. Vias in the power pad of SSOP/QFN packages for example. If I spent some time I might be able to construct things in a way that don't give an error, but that can take too much time. Keith.

Update: I realized that I can make exactly the shape I want by just placing a filled rectangle on the etch layer, then placing a rectangular void inside of that. However, if I make my own "power plane" in this way, placing through-hole parts through the plane causes DRC errors ("thru pin to shape spacing"). The void doesn't seem to do anything wh
