Hey, Mike's a star! LTSpice has done more for the planet than <fill in the
blank>.
I was simulating a Linear Tech dc-dc converter and wanted an easy check on
the FET losses.
It didn't work. Once I got the model recognized, LTSpice broke to a micro-crawl
flashing "defcon 1" in the status line when I ran the converter in the one mode
I was chasing. (It simulates rapidly and cleanly in 'buck', but 'boost' makes
it panic and freeze-crawl.
Oh well. I can 'scope it on the hardware. I'd just wanted to explore a few
alternate FETs--these are getting a bit hot for the sealed box these puppies
will be bedding down in.
Thanks Jim,
James Arthur

That was it Phil. Thanks!
With that change the model works as a .SUBCKT in the .ASC file itself, and also
as a .LIB file with the .LIB command.

Thanks Jim, but it's in the LTSpice file as a .subckt SPICE directive.

I also tried that, using a .LIB statement. Didn't work. That's why I'm
confused--it looks like it couldn't find the file, which was in the same
directory as the .ASC file. It still didn't work when I have a full path
either.
Since I tried the obvious things, I figure I'm missing something simple.
Maybe I made a typo or so such.

I'm at 4.22s. I double-checked--plain right click works fine if the
prefix has already been changed, but weirdly it needs ctrl-right-click
if it hasn't.
