OK, I am confused a little. I understand your point that the VSS layer is not in the routing "pair" and perhaps that is the real problem. It would be nice if the autorouter understood connecting to underlying zones. I will try autorouting and tell it the layer pair is my component layer and the VSS layer and do an autoroute. Then try the same with the component to VDD/VCC3/... layer.
On a related note, I found what I think is a bug. i will try to check the bug list to see if I can find it. My edge connector has several GND pins that are used to supply power to my board. I defined the pin name as GND, no draw, Power OUT. EESchema refuses to automatically connect it to the GND net. I change the pin to Power IN and EESchema immediately says it is connected. The manual says Power IN or Power OUT are supposed to both work to automaticall connect.

A wild guess here, as I've never done anything like that :-) How does the system know that you can get to the VSS layer from the component layer? If things work with a DIP, would placing a via do the same job? It would seem logical to me that if you want to route to an inner layer then you need to place a via between it and the component layer. I'm not sure if this can be done automatically (there is a way to pair layers for via use section 5.4 of the help) Andy On Mon, 15 Jun 2009 00:28:32 -0000 "gregory.dyess" <[email protected]> wrote: > OK, this thing is about to make me pull my hair out! > > I am trying my best to lay out a surface mount board and running into all > kinds of problems. > > 1.
