how to create a runobjfile to plot a family of curves by using ocean skill.

foxest

I use ocean to run the corners analysys, i can save all the corner results,but can not gather the results together to plot family of waves.

Comparing to the corner or param analysys in ADE, i found i do not create a RUNOBJFILE to combine all the results.How to create such

a runobjfile or there are other methods instead? thanks.

that is my ocean script:

ocnWaveformTool( 'wavescan )
simulator( 'spectre )
design（"/home/hlq/simulation/testbench_UX2018B/spectre/schematic/netlist/netlist")
p=outfile("/home/hlq/ocean/result.txt" "w")
cor1='(
"/home/hlq/tsmc/tmodel/ss.scs"
"/home/hlq/tsmc/tmodel/ff.scs"
"/home/hlq/tsmc/tmodel/fs.scs"
"/home/hlq/tsmc/tmodel/sf.scs"
)
tmp='(-40 85)
vdd1='(2.97 3.63)
foreach(cor2 cor1
foreach(temp tmp
foreach(vdd2 vdd1
model=list(cor2 "")
if(cor2=="/home/hlq/tsmc/tmodel/ss.scs"
corn="ss")
if(cor2=="/home/hlq/tsmc/tmodel/ff.scs"
corn="ff")
if(cor2=="/home/hlq/tsmc/tmodel/fs.scs"
corn="fs")
if(cor2=="/home/hlq/tsmc/tmodel/sf.scs"
corn="sf")
modelFile(
    model ""
)
resultsDir(sprintf(nil "/home/hlq/ocean/%fV%dC%s" vdd2 temp corn ))
analysis('ac ?start "1"  ?stop "10G"  )
analysis('xf ?start "1"  ?stop "10G"  ?p "/outp"  )
analysis('noise ?start "1"  ?stop "10G"  ?p "/outp" 
  ?n "/outn"  ?oprobe ""  ?iprobe "/I2"  )
analysis('dc ?saveOppoint t  )
desVar(   "amp" 2u )
desVar(   "vdd" vdd2 )
desVar(   "cpink" 2.2n )
desVar(   "idd" 0 )
option( 'temp  "temp"
)

temp( temp )
run()
ICC = IDC("/V0/MINUS")
GAIN = dB20(value(VF("/outp") 100000000))
noise = abs((rmsNoise(1 940000000) / value((VF("/outp") - VF("/outn")) 100000000)))*1000000000
bw = bandwidth((VF("/outp") - VF("/outn")) 3 "band")
vpink = VDC("/net054")
vin = VDC("/net21")
vout = VDC("/net047")
peaking = (ymax(dB20(clip(VF("/outn") 100000000 3e+09))) - dB20(value(VF("/outn") 100000000)))
LC = bandwidth(clip(VF("/outp") 1 10000000) 3 "high")
PSRR4M = value(db(getData("/V0" ?result "xf")) 4000000)
fprintf(p,  "%dC %fV %s %fA %fnA %fHZ %fdB %fHZ %fdB \n" temp vdd2 corn ICC noise bw peaking LC PSRR4M)
)
)
)
close(p)

  • I kind of figured out a way to deal with this, in case anyone needs it. The best tool to generate the runObjFile is probably the Parametric Analysis itself. To use this, you will have to configure the parametric thing the way you normally do, but in the Ade Analyses list, only leaves dc enabled, which will cost less time for it to simulate. The runObjFile will be available in the tmp directory only after the sweep is finished.
    However, you may still need to put your results into a var-named folder structure manually.
