I keep getting lots of these errors pointing at all my GND connections. I’ve read endless threads about PWR FLAGS and pin input/output but I just cannot get it to behave.
pic below shows example. there are many other warnings(over a thousand!) but I’ll ignore those as they are mostly nonsense.
ironically this circuit us fine - I Have actually built it. Just trying to get it right for the next project…
PCB DRC is all fine - I can get that working nicely
Is there a sensible way to deal with this schematic error stuff in Kicad 8.04?
If it is related to this part of the schematic, then the most likely cause is that you defined the power pins on this IC as power outputs while they should be power inputs. On the AD5293 symbol in KiCad’s default libraries all power pins of this IC are defined as power inputs.
ERC is also a pretty simple and single minded mechanism. It just applies the matrix as defined in: Schematic Editor / File / Schematic Setup / Electrical Ruls / Pin Conflicts Map
If you don’t like ERC, then simply don’t use it. Most often many ERC violations are caused by a few common causes (such as library issues) and it’s usually simple to fix the “mostly nonsense” violations to make the more important violations more visible.
I never run it, but probably it is not the solution you are asking for.
According to what I sow in discussions at forum I suppose that you have probably make some bugs when defining your symbols but from your picture we can see nothing. In errors text there should be probably identified which pin has which type and then the question can be asked if this setting is correct.
The AD5293 is defined correctly - I didn’t change anything.
I guess with a lot of fiddling and editing the ERC it could be made half decent.
I think the " if you don’t like it don’t use it" is probably the best option right now LOL.
That are two different statements and they are probably not correlated to each other. The AD5293 symbol from KiCad’s own libraries looks quite different:
Upload your symbol here, there is something messed up because it does not look like any KiCad supplied symbol I have seen. I made my own back in V5 days for this chip.
The potentiometer pins are all supposed to be passive, so why W is flagged looks odd.
yes- looks like it was referencing an old library folder. I’ve reset paths and rechecked and that part is now fine. Still plenty of other odd errors that should not occur but I’m ignoring those anyway.
I don’t think you should ignore the errors the ERC will catch 'school boy ’ errors and most of the time there is a mistake, besides getting zero errors zero warnings is a great way to proceed with a project
