You must have an *exceedingly* copious library of spice models by now, 
Jim?

119 Manufacturers/Foundries, some, like X-Fab, with 12 different
processes.

Plus all the behavioral models I've rolled myself, probably also in
the hundreds ;-)

From your own empirical results, or constructed from datasheets?

Both.  

Specific part numbers mostly from datasheets, although paying
customers usually provide netlists of the real deal, plus lab-quality
data.

Plus I have tons of functional blocks which aid me in both device
_and_ system modeling:

Like the most recent, hysteresis without feedback.  Those who squawk
that it _requires_ a latch haven't looked at a B-H curve recently...
show me the "snap" (except, of course, those cores designed as memory
elements, and their "snap" is still soft if you look close-up and
personal ;-)

I'm studying the pin out to see if it's a viable device to use for a
translator for conventional logic levels up to 15V swings.

Watch this space ;-)

After 49 years, we finally get models!

I often use opamps as level translators. At lower voltages, LVDS line
receivers.

Looks like I can make a pair of CD4007's work.  

Maybe later today.  I'm still in the throes of the side-effects that
occur _after_ the chemo is done, like itchy hives and diarrhea :-(

I like LVDS... I've designed a few such chips.

I'm still a died-in-the-wool PSpice user.

I've dabbled with LTspice only because some of my clients wanted to
"play along" during their chip design.

Those who simply simulated my .CIR file got excellent correlation.

Those that chose to "draw" their own schematic got overly optimistic
results.

I mused for sometime over how Mike Engelhardt bragged about his speed
advantage over PSpice and every other simulator.

I went to one of his seminars and he touted over and over that his
technique of a special "compiling" of the netlist gave him the
advantage.

Then it dawned.  His "compiling" is going in and replacing every
recognizable "standard" part in the netlist with idealized
equivalents.  Thus the speed "improvement".

You can see his speed advantage fall apart if you feed LTspice with
only components not native to LTspice.

The absence of the Berkeley-Spice-standard .OUT file in LTspice
confirms my suspicions... that would list the actual circuit simulated
along with all the model data, operating points, etc, the whole
shebang.

As for model handling... any Berkeley-Spice-standard model should work
in LTspice (if not encrypted).

(The only way to avoid LTspice "compiling" is to run from another
schematic-capture-generated .CIR/.NET.  If you run from a .ASC you get
the "treatment".)

Oh boy. Well, I guess Mike in his own defence would simply say he'd 
refund you every single cent you paid for it. ;-) 
I hope Mike's not reading this, btw, as from the exchanges I've had with 
him from time to time in the past, he doesn't like this kind of thing 
being openly discussed in a public forum (not surprisingly).

Having met him face-to-face over lunch at one of his seminars a few

I have to agree. If you recall around 2,000 he posted to this PUBLIC NG that 
I had applied to LT, and  trashed my resume in PUBLIC, and hence told the 
world that I had applied for a job whilst employed at TI.  I made an 
official complaint to LT HR that Mike had breached a clear confidentiality. 
17 years on, I have yet to receive any apology from LT. This also says 
something about LT.

Anyway, at least I now have a superior to Mikes LTSpice VDMOS. To wit, 
non-linear cgs, cgd, quasi-sat and subthreshold...

Good!  Maybe then LT parts would be cost-competitive! ;-)

(Reminder what you're referring to: LTSpice is a marketing tool, and as 
such, its development cost is rolled into the bottom line of _every part 
purchased_.  Strictly speaking, parts would be cheaper without LTSpice. 
Presumably, they would get fewer design wins and therefore lower revenue if 
they dropped it, so LTSpice carries on.)

The protection diodes are wired so that those swings wouldn't
be  compatible with low PS voltages.   The 4049 and 4050
would be a more usual solution (no positive-rail clamp on inputs).

In my 4007 voltage doubling level shifter the chip's Vdd rail was not 
connected to any system rails but self generated higher voltage.
