How to print the Monte Carlo iterations results

Micka over 16 years ago

Hello,

I am pretty new with writing ocean scripts.

I have a task to run Monte Carlo simulations and print or save results of iterations.

For example, for each input of CMOS_S_BOX I have to find mean value of leackage cuurent,

but I want to have saved these iteration results in a file...Where am I wrong?::

ocnWaveformTool( 'wavescan )
simulator( 'spectre )
design( "/home/scard/simulation/CMOSSbox_test_new_htype/spectre/schematic/netlist/netlist")
resultsDir( "/home/scard/simulation/CMOSSbox_test_new_htype/spectre/schematic" )
definitionFile(
    "models.scs"
)
analysis('tran ?stop "1u" )
desVar(   "tclk" 1u )
desVar(   "j" 0 )
desVar(   "del" 200n )
option( 'temp "25.0"
'iabstol "1e-14"
'vabstol "1e-8"
'reltol "1e-6"
)
save( 'i "/V4/PLUS" )
temp( 25.0 )
MCresults = outfile( "/home/scard/results/SBOX_mc_htypefinal/sbox_mc_results.txt" "w")
monteCarlo( ?numIters "10" ?startIter "1" ?analysisVariation 'mismatch ?sweptParam "None" ?sweptParamVals "25" ?saveData t ?nomRun "yes" ?append nil)
monteExpr( "leak" "-average(clip(i(\"/V4/PLUS\" ?result \"tran-tran\") 5e-07 1e-06))" )
monteRun()
Imc_mean = average(-average(clip(i("/V4/PLUS" ?result "tran") 5e-07 1e-06)))
fprintf( MCresults "%3.4f \n" Imc_mean*1e9 );
close(MCresults);
MCresults = outfile( "/home/scard/results/SBOX_mc_htypefinal/sbox_mc_results.txt" "a")
)
close(MCresults)

In this bolded area I am obviously doing mistakes, because in the mcdata file I get same results for all 10 iterations, but running an usual MC simulation I am getting different values...HELP, PLEASE!!!

Thank you...

Ok, here is the problem:
monteRun()
Imc_mean = average(-average(clip(i("/V4/PLUS" ?result "tran") 5e-07 1e-06)))
fprintf( MCresults "%d \t\t %3.4f \t\t %2.3f \n" j Imc_mean*1e9 Imc_std*1e9 );
close(MCresults);
MCresults = outfile( "/home/scard/results/SBOX_mc_htypefinal/sbox_mc_results.txt" "a")
)
close(MCresults)
Ok, with this bolded command I get the average value of 400 MC runs, and I wana have in sbox_mc_results.txt results of all 400 MC runs.
How do I achieve that?
If I put only
Imc_mean = -average(clip(i("/V4/PLUS" ?result "tran") 5e-07 1e-06))
it gives me like a result some strange letters.
So, my question is what instruction do I have to use, so I could save average results of all 400 MC iterations???
Thank you...
