Altium (19.0.10) says the following nets contain floating input pins:
But they seem connected (and on grid) to me (see below). Earlier they were directly connected, no luck. I created an empty project, added this schematic and compiled and got the same errors (and a few bonus errors). Also, I don't want to suppress these errors; I want to fix them.
Even if I connect the schematic to its parent schematic (see below), I get the same errors.
Also, I'm getting "Net  has only one pin..." errors/warnings for these pins (and many others) in my top level schematic. I've checked and everything is on grid (and I think I have my buses/taps named correctly --e.g. SDO1, SDO2... SDO12 go to SDO[12..1]).
Again, I don't want to place directives to silence the errors. Any other comments are welcome (I'm an Altium newb).
