Are your unnamed nets connecting ports, nets or busses?

It is my experience that nets do not need names to  work and Busses need to
be named.

I was trying to point this out since I and coworkers of mine have been
bitten by not having a name on a bus that connected two sheet entry symbols
with "Sheet Symbol/Port Connections". The Netlister generated two busses,
one for each page instead of one bus. When the bus was named on the top
sheet the netlister connected the two sheets and generated one bus.

Thanks for the clarification.

A clarification -- wiring to ports is not always "just for the viewer".  I
use "Sheet symbol/Port connections" with a hierarchical project, and often
have unnamed nets connected to ports.

3)   Whichever end you connect a wire to is the hot spot. Or to be more
accurate whatever net has the same name as the port is the hot spot.
Basically all the port does is say that the net on that page with the same
name as the port goes off the page. No graphical connection required.

Ports and Buses are only connected to the nets by the net names, and any
graphical connection is just for the viewer. This is why it will complain
if you have an unnamed net connected to a port, and why a bus between two
sheet entries needs to be named.
