I put 'nc' symbols on pins, so I can get a DRC report of pins I may
have forgotten to connect.  However, I sometimes use a net stub
with a 'netname' attribute as a named port instead of io-1.sym,
input-2.sym, or whatever, since it is kind of visually cleaner and
more compact.  When I use a net stub like that, it doesn't need
any =E2=80=9Cmore touches=E2=80=9D...

Now maybe if I had a better =E2=80=9Cport=E2=80=9D symbol, I wouldn't abuse=
 a net
segment like that.  My main complaint about the port symbols is
that I either need to
(a) put up with an ugly =E2=80=9C:1=E2=80=9D on the port name, or
(b) maintain a visible 'value=3DNAME' *and* an invisible
    net=3D'NAME:1' attribute.

I choose (b) because the :1 is really distracting when pin names
end in a digit, ending up like =E2=80=9CP1_1:1=E2=80=9D, =E2=80=9COUT10:1=
=E2=80=9D, etc.

Regards,
Colin
