what's wrong with the function ocnYvsYplot? |
|
|
Hi, all: I use ocean to simulate an OPA, and I use the function ocnYvsYplot. there have wrong in this two sentences:
val_one=value(ocnYvsYplot(?wavex vod ?wavey derivative) -3.0)
val_two=value(ocnYvsYplot(?wavex vod ?wavey derivative) 3.0)
I do not know why. the .ocn file is this:
ocnWaveformTool( 'awd )
simulator( 'spectre )
design("/home/wjx/full_opa/lfl_SDADC_FULL_OPA_AC/dc_vic/netlist")
resultsDir("/home/wjx/full_opa/lfl_SDADC_FULL_OPA_AC/dc_vic/results")
path("/home/wued/lib/csmc06")
analysis('tran ?stop "2u" ?errpreset "conservative" )
analysis('dc ?saveOppoint t ?dev "/V6" ?param "vic"
?start "-2m" ?stop "2m" ?step "1u" ?readforce "spectre.fc"
?restart "yes" )
envOption(
'firstRun t
)
saveOption( ?saveahdlvars "all" )
saveOption( 'useprobes "yes" )
saveOption( 'currents "all" )
saveOption( 'pwr "all" )
