Saving the results of the Monte Carlo simulation with the Spectre Netlist scripting

Hello,

I want to save each iteration of the Monte Carlo simulation using .print syntax. Because I want then read it using Matlab.

Using the following code, I was happy to save specter results and read them using matlab.

TRN1 tran stop=0.0200u errpreset=moderate write="spectre.ic" writefinal="spectre.fc" annotate=status maxiters=5

print V(Vx1), I(Vx2),name=TRN1 to="VOUT.out"

However, I want to do the same thing for Monte Carlo simulation and print outputs for each iteration.

mc1 montecarlo numruns=300 seed=1 variations=all {
TRN1 tran start=0 stop=0.0200u
}

print V(Vx1), I(Vx2),name=TRN1 to="VOUT.out"

However, I only have a single output file "VOUT.out" for a single simulation (maybe the last one).

Any suggestion?

Dear Jafar,

Have you included the option to save the statistics for all Monte Carlo simulation iterations? Please see the option I have checked in Figure 1?

Did I understand your question and problem correctly?

Jafar,

I think your question is more of a command-line question (rather than running from ADE that Shawn's talking about).

I think the simplest is just to use addto instead of to in the print statement:

print V(Vx1), I(Vx2),name=TRN1 addto="VOUT.out"

You might need to remove the file before you start the simulation though to stop it appending previous runs.

Regards,

Andrew

Thank you Andrew,

I really appreciate your help. That's the solution.

Thank you very much for your response. Actually, I am using Spectre in command-line mode.
