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...

  •  Hello everybody !

    now, i'm front of another problem... when i generated my netlist, i lauched my ocean script on the icfb terminal and its successful until the line where i'm doing a calculation.

     -------------------------------------------------------------------------------------------------------

    ocnWaveformTool( 'wavescan )
    simulator( 'spectre )
    design(     "/home/user/simulation/TB_netlist/spectre/schematic/netlist/netlist")
    resultsDir( "/home/user/simulation/TB_netlist/spectre/schematic" )

    createNetlist()

    definitionFile(
    "models.scs"
    )
    analysis('tran ?stop "10m"  )
    temp( 27 )
    run()
    selectResult( 'tran )

    delay = abs(delay(VT("/A") 0.55 1 "either" VT("/Z") 0.55 1 "either" 0 0 nil nil))
    plot( delay ?expr '( "delay" ) )
     -----------------------------------------------------------------------------------------------

     The underline part doesn't work. The error "can't handle... abs(nil..) " there is no problem with the syntax (its exactly the "save script" from the analog...)

    \e *Error* load: error while loading file - "netlist.ocn"

    Then when i do the simulation by the interface analog environment (manually), its works but there is no waveform just a black graph with nothing inside (no calculation again) and that for all my simulation which worked before !

     

     I need to reboot my icfb terminal and lauch the same simulation by the interface (manually) and its WORK with the waveform ! 

    The problem comes from my script, where i think i might change the environment... and then no calculation is possible once the script is lauched.

    i'm quite sure that it miss a file in the simulation netlist file not correctly or not generated...

    i hope you will understand my trouble !!... if you want more details about that no problem....

     

    thanks !
