Another idea similar to Ian's (5)-- if the footprint's pads don't work well (e.g., it's a large footprint with pads around the edge), you could add tiny (zero size?) free pad(s) in the interior, put them into a pad-class, then use a via/pad-class clearance rule. Unfortunately, the pads will probably interfere a bit with tracks being routed through as well.
Or possibly: 6) Place one or more buried vias within the footprint; depending on the shape of the area to be excluded, you might still need a design rule, or possibly just make the buried vias large enough/close enough so the router can't get a normal via in there without violating your standard via/via clearance. The buried vias won't interfere with track routing. > -----Original Message----- > From: Ian Wilson [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, April 09, 2002 5:59 PM <snip> > 5) You may be able to achieve what you want with a Pad-Via rule using the > pads of JP1.
