how to simulate breakdown voltage of MOS and bipolar cell?

And why i can't find parameters about breakdown voltage simulation in spice model ?

When I simulate the IV curve of MOS , I can't see the phenomonen of breakdown curve!

 

[rajanarender_suram]

what process and upto what voltages ur simulating

Re: how to simulate breakdown voltage of MOS and bipolar cel

I know of some companies with their own proprietary models that allow you to simulate the breakdown, but in standard SPICE you won't be able to simulate the breakdown voltage. Usually the characterization/modelling engineer will not bias the transistor in the breakdown region when extracting models, because this will create greater error in the model where a designer wants to operate the transistor. Thus, breakdown is something that one is not able to simulate accurately or not at all. If there is a technology manual, please refer to that to find out what the breakdown voltages for your transistors will be.

simulate is not accurate
