How do you set a range of ok pins for auto-routing to?

Former Member
Former Member over 12 years ago

I've done some googling for this, but I think I'm using the wrong keywords to describe it.

 

I'm just starting out with Eagle, and throwing together some home-etch breakout and prototype boards. In both cases, either the I/O range of a microcontroller or the pins of some 0.1" header, it doesn't really matter which wire goes to which as long as each goes to one of its own.

 

What I would like to know is if there's a way of saying "here's 9 wires and here's 12 potential pins, sort yourself out", because going back to the schematic every time to change the layout and avoid crossed wires seems like I'm doing it the hard way.

 

The supply tags seem close to this, in that it allows common pins, so I suspect there must be a feature for pin groups/ranges that I haven't found yet. What's the magic command name I'm overlooking?

    A feature you may be after is called "Pin Swap" so check out the HELP for a

    description.

    To use it the library parts need to be set up for it. Specifically the pins

    of the 'symbol' that are part of the 'Device' (Symbol + Package) need to

    have a PinSwap numbers greater than 0. Pins in the same group (swap number)

    can be swapped

    So for a pin header part, give all the pins the same swap number and you

    will be able to swap nets between them while in the Board Editor. Click on

    the pin with the net you wish to move and then click on the pin you wish to

    move it to. The nets will swap. So now the board looks good but now you need

    to go back to the schematic and reposition the nets there as they will be

    all crossed over now. Making them tidy there with no going back and forth

    between the Schematic and Board is a lot easier.

    Thankyou Warren, that sounds like exactly what I was after! I'll give it a go. image

     

    (appologies for the slow thanks, I thought I'd get notification if my question was replied to, but didn't)
