ERC schematic warnings that I am not sure about

unebonnevie

Hi,

 

I get a lot of the below warnings, and I verified my schematic that

things are connected properly.  Why do I get these warnings?  There is

nothing else that I can fix.

 

1. Close but unconnected wires in nets N$10 and VCC

2. Missing junction in net GND

3. Net N$1 overlaps pin

4. Only one pin on net N$1

 

 

For item 2), there is NO junction intended there, but I get a warning.

For item 4), I verified that the pin of the IC is corrected connected to

the resistor.

 

Should ignore these warnings?

 

Thanks

    Hi,

     

    I get a lot of the below warnings, and I verified my schematic that things

    are connected properly.  Why do I get these warnings?  There is nothing

    else that I can fix.

     

    1. Close but unconnected wires in nets N$10 and VCC

     

    You schematic has two wires that may appear to be connected but they are

    not. try the command "show N$10" or "show VCC" to identify the issue. (I

    assume you know that you can click the warning to get the problem area in

    focus)

     

    2. Missing junction in net GND

     

    Maybe two GND wires are crossing, and there is no junction? This is just a

    warning to make sure you know what you are doing. Either remove the crossing

    or add a junction. Maybe one of the nets crossing have wrong name?

     

    3. Net N$1 overlaps pin

     

    The net ends at a pin but is not connected. To fix this, move the device

    away a bit and then back again.

     

    4. Only one pin on net N$1

     

    The net does not have a source and destination. The error is probably

    related to the previous issue and will go away when you get connection.

     

    For item 2), there is NO junction intended there, but I get a warning. For

    item 4), I verified that the pin of the IC is corrected connected to the

    resistor.

     

    Should ignore these warnings?

     

    Not until you are sure they are ok. You are better off removing their cause.
