I created a 4-layer board: Top layer = signal, second layer = gnd, third layer = power, bottom layer = signal.
I drew some gnd-routes with autoroute on second layer and placed some vias close to parts on top layer. Now I am trying to connect some ground pads to those vias on top layer. For some parts it worked, but for most parts/pads the autoroute function treats those vias as obstacles.
Any guess how to solve that?
I’m not an electronics engineer, but aren’t signal layers supposed to be on the inside, encapsulated and shielded from EM noise by ground/power planes on the outside?
Also if you got a full plane dedicated to GND, is it really needed to have ground tracks? I thought one then just puts in a ground fill zone and have more flexibility that way?
sorry for my misleading saying “autoroute”. I just draw single tracks which “route” somehow to the pointed target.
It does not accept the pointed target.
Is there a way to switch this function of “track routing” off, and force a track
to contact a wanted pad or via?
I changed the design rules for vias, making them less strict.
I noticed that some tracks do not have a track name, the vias either.
So, I am trying to edit the properties of a drawn track and of vias adding a net name to them.
I haven’t found a way of doing this yet.
problem solved.
I deleted all ground tracks and routed them again. This time I used hidden vias and made sure to choose the right layers.
Thanks for guiding me in the right direction.
