The plot thickens. One possibility is that Mr. Muehlberg expects something
with a No-ERC directive on it to not netlist.
But we should probably assume that he has placed No-ERC directives to
suppress unconnected pin warnings. Thus his comments would make sense. So
the problem here has *nothing* to do with No-ERC directives; that was a red
herring. Rather, something is causing pins which he thinks should be
unconnected to be connected.
The suggestion to chop the schematic is generally a good one. It can help
to narrow down a problem to a few primitives by doing a binary chop (i.e.,
half, determine if either or both or neither half has the behavior, then
chop again in half accordingly, until only a few primitives are left).
But this may not be necessary. I would look at exactly what pins were
netlisted, and what name was assigned to the net. I would also show hidden
pins and see if there are any that might be causing the problem. It is also
not utterly impossible that someone could assign some wires the background
color; I think it is easy to anticipate what would occur if this were done.
I haven't tried it; Protel should lock this out, but I wouldn't blame then
for not doing it. To detect these, I would select all wires, which should
make any invisible wires visible.
