Anyone have an accurate I-V curve for an NE-2 neon indicator lamp?

(I think it's time I applied TANH to it ;-)

LT Spice already has neonbulb as a component.

As do I, recently posted here. But I'm on a "crusade" to make Spice
models that don't have convergence issues.

What are the topmost complaints we see here about Spice models?

(1) Doesn't match the behavior of the real part
(2) Won't converge, or very slow simulating.

I aim to change that, and make some money from model-making, while I'm
at it.

So, who's going to pay you big bucks for a better model of an NE-2?

---
As part of a nice, inexpensive library of well-thought-out and
executed parts, I suspect the big bucks would result from the volume
of sales of those libraries.

Your mindset of selling a few expensive niche products probably
keeps you from seeing that, and is what'll keep you out of the big
time.

Well-executed parts, like the simple NE-2, or a 4046 that really
works, are simply advertising "teasers" to elicit requests to model
nasty systems, or modeling an OpAmp to match the real world.

Modeling an NE-2 sounds like negative advertising.


---
If it's as difficult as you proclaim, then a good model would be
like a feather in one's cap.


It's difficult because neons vary wildly in their behavior. So there
is no really good model.

But why make a big deal, and spend a lot of time, to model an NE-2?
It's not likely that anybody would care much, and LT Spice has one
already.

Feather in one's cap? Where do you get these archaic expressions?
