HSPICE level 49 model in LTSPICE

HI, I have a level 49 MOSFET model for HSPICE and I want to use it in LSPICE. How I do it, step by step? I mean I'm new in LTSPICE and I've no idea how to modify mos parameters. Thank you very much, this is the model:

Hello,

This model will never run in any SPICE. The model-statement has to start with a period "." . .MODEL CMOSN NMOS ( ....

It's done like in any SPICE. Include the model in your circuit. Name the transistor CMOSN like your model's name and add a length and width parameter to your transistor.

Which parameter do you want to change?

LTspice accepts the model as it is! You have to change nothing on this model.

Below is a netlist from my test circuit.

There is a user group for LTspice with hundreds of examples.

Best regards, Helmut

PS: Has "le_chiffre" at least a first name?

Thank You Helmut, but I have a few more questions :

That's my question! How I include the model??? I tried opening standard.mos and pasting the model at the end, but I'm not sure if this is the right way.

How can I do that?

Yes, of course he has. It's Iñaki. Do you know how to pronnunciate it?

Hello Inaki,

Here are the instructions to use a MOS-model in LTspice.

Don't add models to standard.mos.

Using MOS-models in LTspice

---------------------------

1. Add symbol "nmos4" to your schematic.

1. RightMouseClick on the text NMOS and change it to your model´name, e.g. CMOSN.

2. RighMouseClick on the symbol body, a dialog appears to enter L, W and other parameters.

1. Ctrl--RightMouseClick on the symbol body allows to make parameters visible on the schematic.

2. Add a SPICE-directive to include your model file. .include cmos200.lib

Ignore the very few warnings about parameters.

I have attached the schematic file "cmosn_test2.asc" and the model file "cmos200.lib". Keep both files in the same directory.

Best regards, Helmut

Hello Inaki,

It seems I made a mistake when I edited my previously posted model file. I have added the correct version.
