connecting a Signal to a via in board editor

Hi,

 

Is there a trick to connect a signal to a via?  I can connect signals

between packages, but if I place a via and try to connect a signal to

it, it doesn't take. I had to create a pad as a part to get it to work.

 

Normal behavior?

Hi Martin,

I've run into this problem trying to route traces to Power pads that

leave my board.

You can run airwires between ICs and library components but not simple

pads that you place on the board.

My techniques is this:

Let's say I have a Timer IC whose +V pin I need to connect to the +V pad

on my board.

1) Use airwires to connect the +V pin to some other pin or component

(preferably one that not to close to the V+ pin).

2)Use the Route command and start routing from pin +V, but head towards

+V pad or via.

3) Using the wire command start at the V+ PAD on the board and connect

this wire to the traces you have already routed.

4) Eagle will ask if the two signals go together, select the name you

want the joined signal to have and click ok.

5) Now if you check name you'll see that both the Timer +V pin and the

+V pad are all one signal. If not then check the PAD signal name it

should be the same the wire you used to connect it to the traces you routed.

6) Now that the connection is complete you can delete the dummy airwire.

Hope this helps.
