Overlaps pin - ERC

Question

Hello,

I've just finished my first schematic and after running ERC I got tons of warnings.

They are basically informations about some nets that have overlaps pins in several components.

Other information I got says that nearly all components have unconnected pins, which seems a little weird, once everything appears to be connected.

Would you please give me some hints? It seems to be some kind of wrong configuration.

Thank you in advance.

Bests,

The nets are not connected, merely coincident. This happens if you:

- use the wrong tool (you want "net", not "wire")

- move nets over symbol pins

- have symbols with non-standard grid placement

Try moving one of the symbols you think is connected but ERC doesn't.

You will see that the unconnected nets don't move with it.

Quite often, moving the symbol back to where it started will actually

connect those nets. NOTE: moving symbols onto nets makes a connection,

but moving nets onto symbols doesn't!

HTH,
