SS can't find model?

Sumthin' wrong here? The simulator can't find model N1 or P1. P1's
there, I just didn't include it here. Same for DZ and DCS. The
output says "default assumed" but I think it aborts, whatever
"default" is, anyway.

Try change references on original SUBCKT, from N1 and P1, to N1_XN and
P1_XN.

(one thing I despise on SS is this of adding _XN on models. I think SS
could just assume that model without _?? is plain model without worst
case models)

I did all that.

I don't know wtf it's there for. Pity too, 'cause SS is the only CAD
that comes close to digesting this file. SIMetrix doesn't find the
subckts, just the models and the file was written *for* SIMetrix by
Hans Camenzind. Recently!

Assuming this gets figgered out, that Cap in the subcircuit is
across part of a substrate subckt, i.e., a 1 ohm resistor. It causes
a singular matrix. 1 pf || 1 ohm. increasing GMINSTEPS and SRCSTEPS
doesn't help either.

You need to put all the .models that a .subckt references in the that
..subckt.

SS works a bit differently. It doesn't pass on the whole model files to
the engine, only what's required.

SuperSpice does this, in part, to make WC/MC automatic with no hassle
from the user. There are other issues, which make this approach a
sensible way to do things. Methods are always a trade off.

Doesn't that really f people up? I've seen enough model files where
a bunch of subckts reference a common model to think that might be a
PITA.

..library in each subckt?

So what does SS do when it ignores an unrecognized paameter like 5p
or nk=750m?

It looks like it runs - DC sweep. But the graph is a blank. Connect
an NPN as a diode with an R and sweep the DC supply. How do I ask SS
for the collector current?

Sometimes. As far as all the supplied libraries, they should all work.
In 6 years, I think this is the first time that its cropped up.

Of course you can manually use the automatically included include file
to paste any standard spice stuff to pass completely on to the engine
bypassing the SS mechanisms. The issue is that SS does various bits of
pre-processing before passing it on to the engine.

I've seen enough model files where
a bunch of subckts reference a common model to think that might be a
PITA.

or nk=750m?

The ignoring parameter bit is right in the engine, not SS. Ignored
parameters, are well, ignored.

It looks like it runs - DC sweep. But the graph is a blank. Connect
an NPN as a diode with an R and sweep the DC supply. How do I ask SS
for the collector current?

Oh dear...trivial.

1) Place a test point so that its pin connects to the device pin.

or

2) alt-click on a device pin.

or

3) Put SS into probe mode, then just clik on pin

4) Use the "Signals" tab (docked window on left) and click on the signal
name in the list.

If you place the test point on the device or click the device itself,
you get power plots.

I understand this, but why don't you consider adding option to disable
this?

Some users aren't going to use WC/MC, after all.

Because its too ingrained all over the code now.

For the most part, one doesn't even look at the models. I'm still not
sure just why this is an issue. Its just a name. The schematic labels
for the symbol don't have to show the extra bit.
