I built a Si diode from the old comsol tutorial and now i want to find out the breakdown voltage by reverse biasing the model. I been sweeping the model from from 1 to -170 with 0.1 step bias voltage. I still haven't see any breakdown yet. It is normal for a silicon diode to have a such as high breakdown voltages? i'm currently doing the -175 voltage and still the current vs bias voltage is still flat.

Indeed, it depends on the doping concentrations as well as the geometry of your device. You might want to increase the doping concentration and the voltage breakdown should decrease to lower voltages.
