Hide airwires for same signal on several connectors

e14 Contributor

Hi, all.

 

Since I couldn't find any way to search for an answer to my question, I have to ask here instead.

 

I'm running Eagle 6.4.0 on Win7 64. I'm making a breakout board for a motion controller so I have several cables going between the two boards. On some of the connectors on the motion controller the same power pins are present, so on the BOB I have marked the corresponding pins with the correct power name. But this gives me airwires between the pins on the different connectors. Is there a way to tell Eagle that those are the same signal, but they are connected together off-board?

 

Tia,

Stig

    Hi, Warren.

     

    Yes, I could, but that would necessitate that I find out which components I want to route from which connector first and then change their name in the schematic. I've managed to route this board now and I ended up with only 3 airwires, so not too bad, but it would still be nice if we could mark airwires as being connected offboard.

    As you are only dealing with the BOB it does not matter what the supply

    voltages are called on the other board. So it seems to me you should give

    each of the three separated +5v sources a different name. That will keep

    them apart on the BOB so you can route them. Try +5v_a +5v_b etc.

    Hi, Chuck.

     

    I think you may have misunderstood my question... :-)

     

    I'm only making one board, the breakout board. The motion controller is already made (not by me) and it has 3 connectors that all have +5V and +3V3 and these will give power to the BOB. On the BOB I have also 3 connectors where I have marked the correct pins with +5V and +3V3, giving me airwires between the pins on all connectors, even though I don't need a connection between them on the BOB as they are all being fed by the main board. So the +5V on one connector may feed parts of the BOB, while +5V on a different connector may feed other parts of the board, but this will show me unrouted nets and it also clutters the display, making it more difficult to route the board. If I hide +5V and +3V3, I won't be able to see the connections I do have to route. Routing these non-needed wires on an "offboard-layer" would  work, but that would mean using more layers.

    If you give them the same net name, they they are considered connected.

    Consider changing the name of the net on the remote board.

    i.e., On the main board, you may have a signal called VBATT.  On the

    remote board, you can call the VBATT-R.

     

    Alternatively, use a separate layer for wire jumpers.
