Working with Finfet- Need help

[pdatta]

Hi
I just have started working with Finfet. My project is to find radiation effect in finfet which seems far fetched
right now.
For a starter, I'm right now just trying to get the inverter done using finfet with hspice. I am using PTM 32nm
finfet model card.

The problem is, I am also new with hspice. This model card has a nmos and a pmos sub-circuit (also model parameters).
When I am trying to simulate the whole code of inverter using mos sub circuit, I get the below error code:
**error** (c:\synopsys\hspice_f-2011.09-sp1\tutorial\soinmos1.inc:2) Unknown model type: nmos1
**error** (c:\synopsys\hspice_f-2011.09-sp1\tutorial\soinmos1.inc:2) difficulty in reading input
If anyone of you guys think you can help me then I can give the code if it is necessary.
Looking forward for your replies and appreciate your help and support.

Don't know if this helps, but may be you have to include the devtype parameter, s. this posting.

After making a small correction to the soi*.pm files :

.model nmos1 nmos1 level = 57

should be:

.model nmos1 nmos level = 57

and similarly for all of them (the third word should be nmos or pmos, not a repetition of the second word).

Below is a code for DGNMOS
.include './32nm_finfet.pm'

*.model nmos1 nmos level = 57

X1 (D G 0 0) DGNMOS w=500n l=32n
VDS (D 0) vsource dc=1
VGS (G 0) vsource dc=0.5

* dc dc

*spice commands
.tran 10n 100n
.print tran
.power
.print power
.option post
.end

Thank you so much Jenifer Anand. That problem has been solved already though. But if you can give me some information on SET
impact on finfet, that would be of great help. Information regarding:

1. how to modify the fin height and width from the model card or from the command?
2. anyway of changing the doping level in HSPICE?
3. anyway of measuring collected charge directly of a particular node in HSPICE?
4. any experimental data sheet of the collection time constant and the ion track establishment time constant
of the double exponential SET current source for 32nm and 45nm finfets?
those aforementioned questions, if by any chance, could be resolved or any tips would be of great help.
Thank you again for your support................

Iam working with 32nm finfet PTM model in HSPICE

Iam getting the following errors.

* this is sub 32nm finfet prdictive model
.options post=2 brief
**error** (.\soinmos1.pm:2) unknown model type: nmos1
**error** (.\soinmos1.pm:2) .ends card missing at readin
**error** (.\soinmos1.pm:2) difficulty in reading input

Can any one help me to resolve it.....the first error is already sorted in the previous thread...Can any one help me in sorting the second error?

The 2^nd error actually is self-explaining, isn't it? Seems a .ends statement (or "card") is missing after a subcircuit definition.
The 3^rd error probably is a following error provoked by the 2^nd one.

Hi pdatta,

I hav checked her reply and the simulation was successful.......thanks for the reply
