I don't think so. I don't think any PCB users use LTSpice for schematic
capture: most apparently use gschem. And some use gschem to capture schematics

SPICE has no understanding of pin numbers *at all*. Its abstractions
are grounded in IC design where you have no pin numbers (at least
internally). You'd have to provide a file mapping positional netlist
connections to pin numbers. Another advantage of using a *flexible*
schematic
I'm building a backplane board that will have a processor board (master)
and 8 slaves using I2C across the backplane. Is there any advantage to
placing the pullup resistors on the end of the backplane farthest from
the processor board? I recall installing active termination on the old

How do you dump a gschem schematic to a netlist? I do not see an

Several ways, all using other programs. For pcb (the program) flows there are
gsch2pcb and xgsch2pcb. For others, there's gnetlist.
Remember, gEDA

Ok, it looks like I need to install gshc2pcb.

Symbols are for schematics, footprints are for boards. I don't know what
footprint you need: diodes often use footprints similar to other devices (and I
don't use pcb).

Oh yea I have my own diode symbols I use with it just to avoid issue. Sorry.

But BEWARE... the ALF diodes
Normally when I construct a symbol for a microcontroller or such part where the
I/O pins can have multiple functions, I like to include the alternate functions
in the pin label, like this example from an Atmel part:
pinlabel=PE2 (XTAL2/ADC0/PCINT26)
But... I've run into a part where the list

There's a third now - just use File-Import Schematics
Of course, that doesn't give you a separate netlist, nor did the OP
specify that PCB was the target.

I2C is driven from both ends of the bus, so if you want to use the
pull-ups as terminators, use two resistors, each twice the resistance,
one at each end.
I've never heard of anyone worrying about ringing on I2C though...

I2C pullups are generally a few kohms, far above any practical characteristic
impedance,
