Error  Only INPUT pins on net ...

Former Member

Hello,

 

I have the error Only INPUT pins on net ... twice: for V- IC1A and V- IC1B

 

Honnestly I have been looking for solutions for 3 days and nothing.

 

These errors drive me crazy. If I someone has a solution ...

 

 

Thx

 

Here is my schematic:

    If you look a little further, you can see that there also is only one

    pin connected to these particular nets. (And there are some more

    warnings of that kind.)

     

    Obviously, you didn't /really/ connect the nets to the pins as intended.

    Maybe you used WIRE instead of NET, maybe you tried to MOVE net ends to

    pins, maybe you didn't use correct (i.e. matching) grid settings.

     

    Try SHOW on the nets N$1 and N$4 to see what highlights. If a pin is

    connected to a net, it will highlight too.

     

    Correct your connections, then these errors will disappear.

    The easiest way ti check if you REALLY have made a connection to a symbol

    is to try moving the symbol around a bit. If the connections follow, you

    are connected.

    I realize that this is an old post, but since no one has answered it I'll give it a whack.

     

    By default when you create a part in Eagle pins are assigned with the direction field equal to 'IO'. As such, Eagle will not throw 'Only INPUT pins on net' errors, as it can be either input or output. However, if you change the pin direction to 'input' and there are no pins on the same net that are assigned as an output or IO Eagle will give you an error. Likewise, if the only pins assigned to a net are outputs Eagle will throw a 'Only OUTPUT pins on net' error.

     

    Moral of the story: You cannot have only inputs (or only outputs) on a net. If you're getting this error check the direction field of the pins on that net. Make sure you have at least one input and one output or IO.
