I'm laying out a 16-layer board that calls for unused pads to be suppressed on layers 3-14. I'm accomplishing this by using the "Internal Layer - optional" checkbox in Padstack Editor and the "suppress unconnected pads" checkbox in the Manufacture-Artwork dialog in Allegro. What I would like to do is use the extra room given by suppressing the unused pads for routing. Is there a way to only show the used pads during routing? Ideas of how this could be done (but I don't know how to implement any of them) include turning each pad on or off by layer (labor intensive), setting all pads "off" until connected on a particular layer (or starting with a small pad and then oversize the pad if a connection is made) or somehow backannotating from the gerber files.It seems a big waste to have all that extra room to go unused. Thanks in advance for your help. I'm using version 15.2.brian
The pads will be put out only at gerber level.
But for me, triyng to use the "extra" space" left by removing pads is not a great idea:
you will have issues in order to manufacture the board (you wil be to close of holes)
one way is 2 use different physical and spacing types (e.g. pwr for all power net) and define padstacks only for these types with inner layer pad sizes equal to the drillmake all copper to pwr spacinging on all layers equal to the fab drill to copper requirements (0.2-0.25mm being most common) and assign the pwr types to have precidence over all other types.
That's only for gerber level, but not for layout , can you take advantage of the rest room? I think that's impossible,
