monte carlo simulations - what are they?

monte carlo

can any one tell me what is monte carlo simulations and how does it help in designs? thanks in advance.

monte carlo simulations

Monte Carlo Analysis basically tries to mimic the actual imperfections in the fabrication process. It generates
a bunch of random values for various device parameters like W,L and Vt etc etc .. around the nominal values with specified statistical distribution.
These simulation helps in determining the yield of
the circuit and also in turn the robustness of it.

Re: monte carlo simulations

Thanks raduga_in for the information you gave, how do we specify which parameters to be taken for monte carlo simulations in cadence. Thanks in advance.

How to perform monte carlo simulation specifying Vth (threshold voltage) as a parameter?

MC simulation usually needs a rather complex setup. Perhaps this introduction can help you:

@arunkumar446

Usually monte carlo model is provided by the foundry pdk .. in case you don't have it .. you can write matlab scripts and generate different values of vt with
specified distribution and simulate it ..
