Hi,
I need an appropriate model for HCI. In your "compact modeling and Simulation of Circuit
Reliability for 65-nm CMOS Technology", you present a formula for vth degradation due to HCI.
But I have a problem with the constant parameters presented in table 2.
when I use this formula with the presented constants, vth degradation after 10 years is in nv scale. Also when I calculate the final dimension of this formula, which should be v because of vth degradation, the final dimension is v.nm^2.(sec)^0.45.
would you please help me how I can find the mistake?
I'm looking forward to receiving an email from you.

I think it would be also better if you send this group a direct email. Maybe it is quicker to get a response. Here is thier research group NIMO and Prof. Yu Cao email ID.

Hello, Farzaneh Nakhaee
I have successfully used the model proposed by the PTM group:
http://ptm.asu.edu/reliability/PTM_HCI_Beta.pdf (its the same model of the paper)
You should be careful with handling units. For example φit is in eV while the charge q and the constant K are in Coulombs (look at the first term and the second exponential). Something similar may happen in the computation of the electrical fields E0 and Eox (look at the fisrt exponential).

Hello,
Dear Mr. Andres,
I check it several times. I think I used all the dimensions correctly.
would you please send me your implemented code in order to understand what my mistake is?
thanks for your answers.

Hello,
i have sent to you a message with the code. I hope it will be helpful.
Hello Andrés F. Gómez and Farzaneh Nakhaee,
I am using the below model to emulate the HCI effectshttp://ptm.asu.edu/reliability/PTM_HCI_Beta.pdf
But I am facing the same issue with the units and am unable to get the accurate results. I have checked the units and still getting incorrect results. Any help would be greatly appreciated. If you could forward me the code as well that would make it really easy to fix my issue and continue forward with my work.
Thanks in advance. Hoping to hear soon from you.
