This is true the router does not like shapes.

Here is the picture of the fanout that I got. Maybe it has to do with the fact that I have placed a ground plane (hidden in the picture). All other nets have nice and short fanouts. It looks like Router does not like the ground/power plains (shapes). David Price wrote: Fanout is a local process; fanout rules are not obeyed during active routing. Fanout is important if it serves a purpose to be preserved (like protecting the BGA dogbones). Otherwise, the power and ground lengths are controlled DYNAMICALLY with max_stagger rule. No rule - then no control. Regards, David At 04:49 PM 5/23/2006, you wrote: Why does router create unreasonably long and strangely twisted fanouts for ground and power signals?
