EPSROX is the ratio of the oxide permittivity to that of free space, so it should always appear as EPSROX * Eps0 in equations, eg:
model->BSIM4coxe = epsrox * EPS0 / toxe;
from the source code (b4temp.c). Is there a typo in the equation? Perhaps it used to say EPSOX ( = 3.9 * EPS0 for SiO2) and the equation was changed to EPSROX instead of EPSROX * EPS0 when allowing for other oxides.
