Ok I know this is supposed to be simple but I just don’t understand the errors I am getting in the ERC regarding the power flags, etc. I’ve searched all the posts I can find and other explanations, etc but I am still confused. The concept of the power flag is somewhat foreign to me as it is not used in other ECAD tools I have used. I get the basic premise and it is more for ERC purposes than anything else. I think they look odd on the schematic but that’s ok.
Per the default ERC table a bidirectional pin can connect to a power output pin without issue so after a bit I realized I probably don’t need a power flag on both GND flags shown below and that may be driving and issue.
I deleted one and re-ran ERC but get this:
The error moved to pin 8. It’s just not clear to me what the conflict is. If I remove the power flag from all GND connections (I don’t think this is right) then the error moves to some other location in the schematic where two inputs are tied together (GND flag pin is power input) and not driven by anything. Oddly enough it only balks at one location not the 20 where the same situation exists.
Any help would be appreciated so I can move into layout without worrying about the ERC errors. I have checked the netlist and all power and grounds are tied to same net respectively as expected so I probably can move on without fixing it but it is bother me nonetheless.
