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

    You may have inadvertently turned off or changed your grid settings or

    have a library part that is not 0.1 inch grid. The only way to verify

    that things are connected properly is the 2 methods Morten mentioned:

    move the part and see if the nets all move with it or use show to

    highlight nets.

     

    It's easy to get errors like this even if the grid is correct, that's

    why we have ERC. Mostly, they arise from editting connections, it's

    often better to delete and redraw nets rather than move them.
