Link between analog environment and schematic by ocean script

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.

so i can't generate automatically a netlist with the IC5141... (?) there is no other way? or its because i use design( "" "" "") instead of design("path")

edit: finally, i tried to use the script, lauching it under icfb terminal and it works ! in the oceanref.pdf, it noted that design("" "" "") can be used only using icms or icfb ;) but it seems to work on the IC5141...

thanks a lot Andrew

Yes, use "icms" or "icms -nographE" as I said earlier. You don't have to use the ocean executable to run OCEAN scripts; they run perfectly well within the icms, msfb or icfb executables.

In IC61X, the individual executables have gone away and replaced by a common virtuoso executable, and in fact ocean is now just a wrapper around virtuoso. But in IC5141 you can do it by just picking the right executable which has netlisting capability.

 ok thank you for your information ;)

 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...)

***********************CDS.log***************************

**********************************************************

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....

Do you have the ADE window open at the same time as trying to run the OCEAN script? It's possible they're interfering with each other...

Otherwise, it would be best to contact Customer Support so we can work through this properly and see your data.

Andrew.
