Link between analog environment and schematic by ocean script

OLyonnais

 Hello !

i have a problem i would like to create a netlist from my schematic, and simulate it without doing Tool>Analog Environment ..

I have seen that when you do that by the graphic interface, it's generate automatically in your directory: simulation/spectre/cellview/schematic/netlist/

i want to do that by the ocean script, and the command createNetlist() generate only the input.scs but no the netlist file...

I think that the "design" command need to be set correctly... before i used design("/home/user/simulation/TB_netlist/spectre/schematic/netlist/netlist") but now i think i need to use design( "user_lib" "TB_netlist" "schematic" "a")isn't it?but it doesn't work on ocean, the error message explains to do that on icms or icfb window !

 ****************************HERE AN EASY TEST*******************************************************

ocnWaveformTool( 'wavescan )
simulator( 'spectre )

design( "user_lib" "TB_netlist" "schematic" "a")
resultsDir( "/home/user/simulation/TB_netlist/spectre/schematic" )

createNetlist()
definitionFile(
    "corners.scs"
)

analysis('tran ?stop "10m"  )

run()
selectResult( 'tran )
plot(getData("/Z") getData("/A") )
delay = abs(delay(VT("/A") 0.55 1 "either" VT("/Z") 0.55 1 "either" 0 0 nil nil))

thank you for your answer...

  • In IC61X  you can use the "ocean" executable to do this, but if using IC5141, you can't because the ocean executable does not contain netlisting capabilities.

    If you use:

    icms -nographE

    you get something which has the same capabilities as "ocean" - i.e. an ASCII prompt, but yet  you can still plot waveforms and so on. If you do it in that, then your script above will work. You probably don't need to give the fourth argument to design() - that's optional.
