Monte Carlo - Temperature sweep

Renju R Thomas

Dear all,

I need to do monte carlo analysis for my Temp Sensor Circuit.

I tried the dc sweep ........

.DC TEMP 25 125 1 SWEEP  MONTE=100

But the output is not the one expected.

As,

.DC MONTE=100

and

.DC TEMP 25 125 1

are working fine and the output is as expected, I doubt whether we can combine temperature sweep with MC analysis.

 

I also tried, 

.DC TEMP LIN 125 1 125 SWEEP MONTE=100

Please help. 

Thanks & Regards,

Renju 

  • Renju,

    What simulator are you using? That's not spectre syntax (certainly not for monte carlo). With spectre you'd do something like:

    mnt montecarlo numruns=100 variations=all {
      dc dc param=temp start=1 stop=125 lin=125
    }

    See "spectre -h montecarlo" and "spectre -h dc" for more details on the syntax.

    If you're using a different simulator, please say which (and bear in mind that this is a Cadence forum in case you're using a non-Cadence simulator...).

    Regards,

    Andrew.
