Hi
I have problem in running nested parametric analysis in ocean script.
Single loop parametric analysis is OK.
With nested loop, it shows problem. The ocean script is generated from ADE Parametric analysis window with FILE->Save Ocean Script (See below)
analysis('tran ?stop "6n" ?errpreset "conservative" )
desVar( "b1" 1 )
desVar( "b2" 0 )
desVar( "b3" 0 )
desVar( "b4" 0 )
desVar( "vctl" 0.65 )
desVar( "vddd" 1.0 )
desVar( "b0" "vddd" )
envOption(
'analysisOrder list("tran")
)
save( 'v "/vcoout" "/vcooutb" "/I2/ring<0:2>" )
converge( 'ic "/I2/ringc<0>" "0" )
temp( 27 )
paramAnalysis("b3" ?values '(0 1.2 )
paramAnalysis("b2" ?values '(0 1.1 )
paramAnalysis("b1" ?values '(0 1.2 )
paramAnalysis("b0" ?values '(0 1 )
paramAnalysis("vctl" ?values '(0.4 0.5 0.6 0.7 0.8 0.9 1 )
)))))
paramRun()
The first run is OK. for the variable value of b3=0, b2=0, b1=0, b0=0, vctl=0.4
However, for the next loop, where b3=0, b2=0, b1=0, b0=0, vctl=0.5 it shows problem.
The error message is
Opening the PSFASCII file
../b3=0,b2=0,b1=0,b0=1,vctl=0.5/psf/subckts.info.subckts ...
t.ERROR (ADE-4000): Cannot complete the simulation run because there seems to be some problem with the
Spectre executable. Ensure that the Spectre installation is correct and then rerun the simulation.
For further assistance, contact Cadence Customer Support.
Delete psf data in /home/kims/simulation/ringvco_alt1_sim_sk/spectre/schematic/b3=0,b2=0,b1=0,b0=1,vctl=0.6/psf.

Warning from spectre.
WARNING (SPECTRE-17101): The value 'psf' specified using the
'checklimitdest' option will no longer be supported in future
releases.
Can anyone help me?
