$ifimpact_ion is a function to turn on the impact ionization. It is a field and current dependent function which will rely on the electric field in the simulation program.
The impact ionization generation rate is decided by
Gimpact=-absjn/ELCHG*impactratelayer(1,indEl)*&
exp(-abs( ((impactratelayer(2,indEl)*absjn)/productEJ(1))**impactratelayer(3,indEl)))
