In order to apply a Gaussian distribution to a device parameter for Monte Carlo simulations, I have to use a line of code such as the following in the model file:

vary vthnmis_rf dist=gauss std=1/1

This came right out of a real model file from a TSMC process. **Can anyone tell me what the units on std are?** vthnmis is a quantity that is added to vt, and it should be in volts. Standard deviation can't be in volts, so I am not sure what it is. I know that I want to set it to 50mV.

Thanks
