Part IC1 has uninvoked gate EXP with unconnected input pin EXP16

sayyedabbas722

Hello  everyone

can someone help I got two errors in ERC check ,This erroe as follows

1.Part IC1 has uninvoked gate EXP with unconnected input pin EXP16

2.POWER pin IC1G$1 AVDD3 connected to 3.3V

I don't know how to solve this  error please i got in my design process.

  • Error #2 is not actually an error, it's just the software complaining about you attaching a power pin to a net not labelled V+ or V- (if I remember the default EAGLE naming conventions correctly.) Historically, EAGLE schematic symbols for op-amps and other ICs often did not explicitly include the power pins unless they were specifically invoked, and the power pins would be automatically connected to the properly labelled supply nets. This mechanism is still present in EAGLE, and it's at the root of the error messages you're seeing.


    Use the "Invoke" command on IC1 on your schematic, and any hidden pins should appear for you to place. You can then do any additional routing that's needed. If the uninvoked pin isn't something you need for your design (or to make the part work), you can just approve the error.

    Not quite. Eagle expects the power pin to be connected to a supply net

    that has the same name as the pin and warns you if it isn't.
