I have a simple common circuit, (see attachment) with a linear converter and anti-reversing diode. When I do the ERC check I get the dreaded “Pin not Driven” error at the diode. Remove the diode and I no longer get the ERC error. The diode was selected from the “stock” symbols and the pins on the diode are “passive”. I believe this is set up as it should be–any ideas?
I however have a guess about what is going on. KiCad sometimes reports the pin not driven error on the wrong pin. In reality it should point to the power symbol itself but for some reason points to some other pin on the same net. See https://gitlab.com/kicad/code/kicad/issues/2594
The ERC is complaining about the input pin to the DC-DC converter–but only when the diode is present. It is as though ERC does not render the connection between the converter and the power input.
