LT Spice problem

[[email protected]]

I'm trying to add the models of a couple of N-FETs I use to LTSpice. I'm
getting a simulation-time error that I can't resolve. Any ideas? Thanks.

The error:

|M1: Only a level 9 B3SOI can have 6 nodes

It thinks I have six terminals on my transistor and only SOI models have that
many? Looks like only three to me.

I don't have your symbol so can't run the subcircuit. But when I use
just your NMOS model it runs. You have to give V1 a voltage and the LED
still needs a model as well.

No, no, the one with the bikini

Hello krw,

I don't have your Mosfet-symbol, but I have been able to get it working.

1. The subcircuit definition was wrong. Below is the corrected line.

* D=10 G=20 S=30
..SUBCKT DMG1012T 10 20 30

2. Most of th models for power-Mosfets are subcircuits.
Therefore you can use the normal symbol "nmos" or "pmos" with a very small
modification.

Place a symbol "nmos" on the schematic.
Ctrl-right-mouse-click on the placed symbol.
A dialog will pop-up. Change Prefix:MN to Prefix:X
OK.

The attached example has bias point data flags on the nets
to better show the operating point.

Best regards,
Helmut

It seemed to do something here at home. I didn't have time to look at it
today. Maybe tomorrow they'll leave me alone so I can get back after it.

Just use the model alone. Package parasitics don't matter unless the LED
has to also send out GHz pulses ;-)

You can enter a ramp for the voltage source, then you can always see
where it loses steam.

Thanks, Helmut. I still have something messed up. It can't find the model. I
should have time to work on it tomorrow.

Well it is in a GHz field, but I don't think I care about buzz.

It's not getting that far. I must have something messed up with the
installation. It can't find anything now.

Oh-oh, you crashed LTSpice? I though that wasn't possible. Might have to
re-install, it is fairly painless. I have to do that once in a while
because the LTSpice updater doesn't work.

Not crashed, just edited or changed something I shouldn't have, perhaps.

I though that wasn't possible. Might have to
re-install, it is fairly painless. I have to do that once in a while
because the LTSpice updater doesn't work.

Really? It wanted to update my home copy but I didn't let it.

 

[Joerg]

Unless you literally mucked with files in the LTSpice install directory
it's nearly impossible to break.

Really? It wanted to update my home copy but I didn't let it.

It always freezes up for me but it might be related to security settings.

 

[Joerg]

Not surprising. When it comes to software you have a black thumb.

I can't remember when I first installed LTspice. The Updater always
works.

Probably related to security settings. But it doesn't matter, this
software is literally bug-free (unlike others ...) and I only need to
update if a new must-have feature appear. Then it's rather quick and
easy. Uninstall, re-install .. get coffee .. hop back into seat.

 

[Joerg]

I don't run a firewall... that's what a good router is for.

Go to http://www.grc.com and run Shields Up and see what you get. I
get a 100% Stealth Rating.

Thanks, but I don't want to re-install half of my computer stuff here. I
get no viruses or any of that and if this is why the LTSpice updater
doesn't work it's ok. As I said, install by hand is painless. It is so
fast that I don't even have time to snatch a cookie out of the fridge
(although I'd like to).

Did you run Shields Up?

The computation machine bucks upon clicking "proceed" here, meaning it
won't continue:

Gawwwwd! What is it you have screwed up on your machine? You're
probably running Windows Firewall ?

No. It's just very safe

Seriously, yes it will balk at web sites that are overly intrusive but
those are web sites I am not interested in anyhow. So what's the
problem? All they can find out is my connection IP and maybe track that
to find out my preferences. Only to discover that it's gone the next day
because I turn off the modem at night and it is dynamic IP.

It's similar when some spammer sends me an email with infested
attachments -> kersplosh ... gone.

If someone were interested in watching x-rated stuff on the computer
they would decidedly not be happy in this here office. Because most
likely it won't work.

Hmm, how can that be installed separately? I always did a clean swipe
and re-installed the whole LTSpice chebang, hoping that this would also
fix the updater. But it never did.

It might really be the firewall or something though, in my case.

Zonealarm just indicates port 53, which is DNS and Http (80). Might
want to check your DNS settings.
Otherwise the Updated can't be installed seperately, a full install is
needed.
