Monte-Carlo Simulation - What can be wrong? (cadence - spectre)
Apr 09th, 2009, 1:34am
 
Dear all

I have been running an extensive monte-carlo simulation that took 2 days. What I basically did was first running a transient simulation, and and then using the statistical tool of cadence virtuoso, I chose the simulation that was done, changed the libraries for the monte-carlo section, and runned the monte-carlo simulation through the statistical tool (choosing both mismatch and process variations). But the results weren't different from the previous simulation at all.  :o
So I don't believe it can be right.

What can be wrong?  :-?

The valuses of parameters in Montecarlo simulations are determined by seed value. If the seed values are same values of paramenters in all N iterations will be same in any two Montecarlo simulations.

Check seed value
Thanks
