Re: Copper Plane short between +3.3V and GND

I got it now. Thanks for your help. I stumbled through it some how. Ill probably forget how to do it again if I have to do it again,
Sorry for all the trouble.

Re: Copper Plane short between +3.3V and GND

Tom I am still struggling with the procedure. I assume I start with the first picture and follow the arrows, which I did. However, if I was suppose to start at step 1 and then the pictures then I probably followed it wrong. Also, the final result I am trying to reach is: Signal layer 1, GND plane th...

Copper Plane short between +3.3V and GND

On layer 3 there is a short on +3.3V and GND. I can not find a way to fix it. Only GND should be connected to the 4 thermals.

Re: Copper Layer Order

Tom, There are four traces which are locked on the top side of the board. These traces have the same exact same length and will be adjusted to maintain 100 ohm characteristic impedance (which I wonder if Dip trace supports?) So starting from un poured planes and the four locked traces, here are my s...

Re: Copper Layer Order

Tom it looks like everything is fine, but I did Verifying\Check Net Connectivity with traces, nets, and pours checked. It said +3.3V and ground are merged and to run DRC for details. So I ran DRC Design Rules and it finds no errors. So if there is truly an error, how do I find it.

Re: Copper Layer Order

Tomg
I think all of the pours are good now but the auto router can't even come close to routing it.
Obviously, I am missing something.

Re: Copper Layer Order

Yeah, I see that but so far I haven't found a way to have the GND connected to just the ground plane and the +3.3V just connected to the +3.3V plane.

Copper Layer Order

I have a board with 4 copper layers that I want to have in the following order: Signal 1 GND +3.3V Signal 2 I looked and found 3 places to try to set my order but none worked for me. The water fall up and down arrows took me for a loop. I could not manage to do much with it. I appreciate any help. I...
