Does kicad DRC check for single node nets?

Asked by Nimo

Hi all,
I have just been working through a PCB and noticed that I had a net connected to the pin of a chip, but that was it there were no other connections to that net.

I expected the DRC tool in PCBNEW to pick this up but it didn't seem to?

Is this correct (if so is it possible to have this feature?) if not should I report it as a bug?

Kind regards
Nick

It's checked in eeschema, not in pcbnew (that's the reason for the
no-connect tool)

Ok did a little more digging, I'm not surprised that an error such as that would be picked up by the ERC as opposed to DRC check, though I hadn't spotted it when I ran the ERC. Though from having used PADS in the past I'm used to it being picked up at board level. (my problem, not Kicads :-)

I must admit I don't get on overly well with the ERC checker again mostly my own fault. Is there a list of pin type definitions anywhere? Most of the such as open drain are obvious, but I always struggle with power, for example is GND on a uC a Power in or power out pin? Logically it's power in, and in terms of electron flow it's power in as well, but the latter case would then make VCC a power out pin arghhh lol.

I'm guessing power out would normally be used for the output pin of a voltage reg?? But a list of the official definitions would be great :-)

Either way, you've solved my original question so I've marked it as such.

Once again, thank you for your help Lorenzo :-)
