Simulation not working, no result shown.
Closed | Responses: 0
Hi, I'm trying to run the simulation with default setting and no result is presented. Could someone please help. Thank you.
Is penetration of electron in oxide considered in calculation?
I'm trying to develop a SiNWT simulator ( :P) based on mode-space approach. I'm using OMEN WIRE in order to compare the results that I get. I feel the OMEN model...
problem launching job

sir why do I get the following error:
Problem launching job:
Program finished: non-zero exit code is 1
can't read "total_vstep": no such...
Getting Exit Code 1
Why is this problem happening??
Program Finished :Exit Code is 1
Can’t read “total_vstep” :no such variable

While running a simulations, after some time getting this error:
“Problem launching job:

I didn’t change any default setting, but the tool is not performing the simulation.
I’m getting the following error when I run a simulation:

How to do simulation on OMEN nanowire tool?
Open | Responses: 3
I have changed some input values and tried to simulate the structure but, it was taking around 3 hours to get simulated. Is there easy way to simulate nanowire structure using OMEN Nanowire...
How is the continuous doping density profile implemented in omenwire?
Open | Responses: 1
I understand that to mimic the contacts we enforce a high doping density in the source/drain extension regions, and it is easy to do so in a continuum formulation, like the effective...
Why does the potential show a singularity at the location where the boundary condition changes from Dirichlet to Neumann?
At the gate side, there is a change of boundary condition from Dirichlet to Neumann as we move from the gate to the insulator. Mathematically, this will lead to a singularity in the solution...
boundary conditions for the poisson equation
Open | Responses: 2
I have simulated a case where Vg = 0.4V and Vd =0V. However, when I look at the potential plot, it appears that the potential at the boundary where the gate is 0V. Is it simply a plotting...
analytical expression for the poisson solve
May I know what is the rational behind the use of the analytical expression given in the answer I asked about the convergence criteria. In particular, is the analytical formula based on the...
In the input deck, the poisson convergence criterion is stated as 1e-3. What exactly is the convergence criteria used in omenwire? How much additional computational time will I need if I...
In determining the electron density, what fermi levels did you use at the source and drain?
Default voltage values need be changed.
With the default device specifications, it seems that the default nanowire has a threshold voltage of ~ 0.6V. So, to drive the device into deep ON state, one should apply gate voltage, probably...
OMEN Nanowire Supporting Document
23 Feb 2009 | | Contributor(s):: SungGeun Kim, Gerhard Klimeck, Mathieu Luisier
This material supplements the first-time user guide for OMEN Nanowire with details concerning the limitation of the tool at large gate voltage. At large gate voltage, the calculations of the drain current can be incorrect when the Poisson solver in OMEN does not converge. This problem is not...
