Auto Router 4 layer PCB
87 5

Hi to all,                 I make a 4 layer pcb with inner1=1.8VCC and inner2=1.2VCC. When I choose the Auto Router (instead of using vias to connect each component at 1.8VCC or 1.2VCC) it uses tracks to do the connections according to the DRC. Why? Why is not using the inner layers (using vias instead of tracks)? Maybe im not using some configurations?

Hi You have already posted about this and had some help from Support. If you need more help then you must read: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) and make your project, or a copy of something that illustrates your question, public.

Sorry about that, I forgot the picture. ![auto_router.png](//image.easyeda.com/pullimage/8pCXIuo48NcEFEw29FWSogNp3tENfsBJQDfE7xr5.png) As you can see pins that must be connected to inner1(1.2VCC) or inner2(1.8VCC) using vias, are connected with tracks. The layer configs are: ![auto_router2.png](//image.easyeda.com/pullimage/0cKHmLV2i6l3718UzPloVY8JlVD312BSuq8JiavD.png)

@GastonMelo, The pictures help but do not give enough information. Please make a copy of the pcb and then hand edit the area that you have pictured above to show exactly how you want it to be routed. Preferably, do this **and also** share your project publicly or via the Team function with support.

Maybe I not explaining myself correct: Here goes: 1) I made 4 layer pcb, and im using inner1 as 1.2VCC plane and inner2 as 1.8VCC plane. 2) If I use autorouter every pin at 1.8VCC or 1.2VCC in the board (picture reference) is connected using tracks (as picture). My questions : 3) Why is not using vias to connect for example every pin at 1.8VCC in the board to inner2? 4) Why is not using vias to connect for example every pin at 1.2VCC in the board to inner1?

@GastonMelo, Your explanation is good but you have to consider that you are asking a complex question on a forum where english is not necessarily the first language. A picture is not only worth a thousand words but it is universal because it is worth that in any language. :)
