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 would also like to do something similar. I even have a runObjFile but the simulations are only indexed by run number. I would have liked to add the swept variables as well so that I could plot the results versus one or the other swept variable. Unfortunately, I don't know the syntax to use for manipulating the runObjFile. My attempts at tinkering were not very useful. Any suggestions on adding parameters to the runObjFile would be welcome.

    You can see an extract from the "doctored" version of my runObjFile, where I tried to add sweep variables "var1" and "var2".

    Thanks,

    Vivek
