I’m porting some OrCAD schematics and noticed they used a crafty power symbol convention that’s new to me. The bar and the arrow are the same net, but the arrow is only used once and indicates the power source.
This, plus I realised that some nets don’t require a PWR_FLAG because they’re already connected to a Power Output pin. So I end up with a confusing combination of bar and sometimesPWR_FLAG, which I don’t think has an obvious relationship with the original.
I’ve drawn new symbols to match the originals, and then added PWR_FLAGs in the KiCad-suited way. A bit weird, but no weirder than the original, and clear once you know (which a bit of descriptive text could accommodate). Plus you get the KiCad ERC benefit.
