ERC error for power jack? Answered

Picture of

I can't get past this ERC error check:


Researching for answers I found where they say to use the "INVOKE" command ; however that just leads to another error. "Part has only 1 gate: CN1"

Not sure what to do. Suppress the error by clicking "Approve" ? That kind of makes sense since it's an external power source, however I'm not too sure cause I don't quite understand this error.

Hi Robert,
Thanks for you participation on this forum, I will do my best to answer your question. Seems that the part you are using contains a power pin called GNDBREAK. This error doesn't mean it has an implicit pin, just means this power pin doesn't have an accompanying supply pin. EAGLE expects that power pins have a supply pin placed in the schematic with the same name. If you click the ADD command you will notice we have 2 supply libraries which you will be able to select from. I searched the Supply Libraries I couldn't find one with a matching name. Placing any supply pin from the supply library and changing the name will not work.

You will need to consider making a part or edit an existing one and change the name of the pin to match the name of your missing power pin. In your case you would name this pin GNDBREAK. Then place this part anywhere on the schematic, doesn't need to be connected, just need to be placed somewhere. This will satisfy this error and clear your ERC.

Now that I explained how to fix it, I would like to share my opinion. Manually connect this pin to the appropriate power network on your schematic. From the screen shot it doesn't seem to be connected. After manually connecting it, then you can approve this error. Once you transfer to the board, you can verify the connection on the board.

Sorry for the long winded answer, just wanted to make sure you understand what is going on.
Have a GREAT DAY!!
