Complete but incomplete?

tomstorey

Working on a PCB design, and Ive completed  the layout, but Eagle is telling me there are seemingly some things that still need to be done.

 

Take the attached screen shot for example. Ive selected a net, which highlights all of the nearby pads/traces etc that are part of it. But there are airwires telling me I still need to connect something?

 

Can anyone tell me why this would be happening, and perhaps how I can get rid of them (short of connecting them the way it thinks I should, which would spoil my design.) image

 

Thanks!

    Indeed I did duplicate blocks of circuit in my schematic. In this case

    the parts in question all share the same net name on purpose (+5V in

    this case, and one between two pads/traces part of the GND net). But

    although I have connected them all together, and in the screenshot I

    have highlighted the net named +5V and it has highlighted everything

    correctly, its still telling me that I need to connect them together.

    It doesnt seem happy with the way Ive done it, even though it would

    appear to be valid.

     

    Eagle doesn't know you intend your copies to be treated independently.

     

    As Rob already explained: manually named nets (especially those

    connected to power symbols) in the schematic don't get renamed when

    copied.

    So your 'independent' sub-layouts share them and eagle therefore shows

    air-wires connecting them.

    Hi Lorenz,

     

    In Tom's case I think he is actually intending the copies to be connected and not independant. It looks like this is a bug that I have seen only a couple of times where EAGLE has a bit of a moment and draws air wires for nets that are already connected.

     

    Best Regards,
