Hello~I download 32nm model of finfet from website http://ptm.asu.edu/.
.param pnch = 2e16 nch = ??? (what nch means?).param ptox = 1.4e-9 we know tox = Oxide thickness.param ptsi = 'tbsi' tsi = Fin thickness.param ptbox = 1.4e-9 .param npvthf0 = 0.29 npvthf0 = ???.param npvthb0 = 0.29.param esi = 11.7 esi = ???.param eox = 3.9 eox = ???.param nlambda1 ='(-1)*(ptox/(ptbox+ptsi/(esi/eox)))'.param nlambda2 ='(-1)*(ptbox/(ptox+ptsi/(esi/eox)))'
.param delta1 = 0.008.param delta2 = 0.008
.param Voff2=-0.09.param N = 0.2.param Vt = 0.0259.param Voff1 = 0.0
I have a FinFET model parameter and I want to use to simulate a circuit.
I want to change some parameters from the table. (like .param ptox = 1.4e-9 => .param ptox = 1.6e-9) How can I do it?

Hi Mr. Beckett,
I've try to do the same, but I get an error about the level of the model cards:
ERROR (SFE-1138): "*********20nfet.pm" 4: Model `nfet': nmos level 72 is not supported.
Actually, the model file starts with following:
.model nfet nmos level = 72
Thanks in advance for your help
In reply to lartola:
You need to use MMSIM10.1 or MMSIM11.1 - you must be using too old a version. I just tried a very simple model card with level=72 and it is correctly recognized as bsimcmg in either of these two versions. I know that early MMSIM10.1 versions didn't recognize level 72. For the versions I had available to test, it works in 10.1.1.181.isr12 but not 10.1.1.070.isr6 - so it changed somewhere between the two.
can you please mail me The 45 nm FinFet model files to me. I'll be using them for academic puposes.this post has helped me alot.my id is email@example.com.
thanx in advance :-)
i downloaded 32nm sub-circuit model for FinFET (double-gate) and i did simulation in Tanner Spice i am getting proper output for Double gate inverter
now coming to cadence how to include these files(in which format) in the library, in our lab we have analogLib, gpdk45,90,180nm lib
from analogLib library we can instance synmbol for nmos, pmos and we can design our circuit by changing the l and w
can you help me how to instance symbol for 32nm FinFET such that we can change w and l like MOS
help me in this regard
thanks in advance
In reply to venkateshjutur:
I don't think there is an example transistor in analogLib with appropriate parameters for a finfet. You'd have to roll your own - which to be honest would be the normal practice for any technology. People don't usually use the actual transistors from analogLib for anything real - because they are intended to be ideal components.
Can you please mail me the 45nm model card? I need it for my academic project.This is my mail id firstname.lastname@example.org
It would be a great help to me if you can mail me.
