Warnings in schematic that I don't know if serious enough.

e14 Contributor

Hi,

 

I always eliminate warnings, but I have the following warnings,

especially the first four and the two before the last ones are the ones

I am unsure with.  Please see attached picture.  Basically:

 

1) The first four are meant to be only overlap NOT connected.  That's

what I want, but Eagle gives me these warnings.  Why?

 

2) The two "POWER in PIC1" warnings (the two before the last one) are

really mean to be connected to the Vout 3.3V.  Why eagle is giving

warnings on this?

 

Thanks for any advice.

    For all goes: click on the error and eagle shows the spot, then zoom in

    on it.

    Close..., you have a net crossing where a (former) bend has been or

    plural net pieces. Move the nets temporary.

    Net overlaps..., your net does not end at the tip of the pin but goes

    further on to the body.

    Power pin xxx connected to yyy..., eagle awaits a power named yyy on

    that yyy pin and asks you precautionary if xxx is correct.

    If a pin "touches" an alien net, these warnings are generated. You might

    want to move the part and/or net slightly to gain more distance.

     

    2) The two "POWER in PIC1" warnings (the two before the last one) are

    Power Pins are implicitly meant to be connected to equally named nets.

    Everytime you connect them to differently named nets, such warnings will

    be generated. In mixed signal designs, you get zillions of such warnings

    (say: VCC, VDD, V+, VBB etc. of several devices all are connected to +5V

    - and the DRC complains). You can safely ignore/accept them as long as

    you know the connections are correct.

    IMHO this is not necessary. Screenshots can easily be sized below that

    limit (using GIF or PNG with reduced colors).
