Setting too low, too high, or a too great difference between the magnitudes of the values, is not recommended, the same way null values can be problematic. To avoid this, you can simply set Vfwd=1m Ron=1m Roff=1G and you're set. It's unlikely these values would interfere too much with your circuitry. If you want to avoid possible 'hiccups" due to the ideal sharp knee in the transfer function, you can also add epsilon=1m revepsilon=1m to force a convergence-friendly quadratic region. ilimit , though useful, should be used with care, as it can cause problems due to the forced limitation.
