I encounter a problem when i run pss pnoise with ocean script.
I can plot the waveform with the command plot(i("/R0/PLUS") ?result "pss-tran.pss")) in the CIW.
But when I run the i("/R0/PLUS") ?result "pss-tran.pss") it shows the warning as following.
>>
WARNING (OCN-6055): The output '/R0/PLUS' you selected does not exist.  Type outputs() to see
       the list of available outputs or type help('i) for more information on the 'i' command.
nil

So, i can't further clip and average the waveform of i("/R0/PLUS") ?result "pss-tran.pss").
It gives the error like
>>
*Error* clip: can't handle clip(nil 9.9e-05 0.0001).

But the pss and pnoise analysis are completed sccessfully. and I can plot phase noise and pss-tran result.
The problem is that I can not clip the current waveform of /R0/PLUS and average it since it returns nil.

How can i fix it? I post the code here.

....
resultsDir(strcat(resultDir "/" designName "/spectre/config"))
....
openResults(strcat(resultDir "/" designName "/spectre/config/psf"))

when(v("/extal" ?result "pss-fd.pss")

ibias = average(clip(i("/R0/PLUS" ?result "pss-tran.pss") 0.000099 0.0001))
....


More interesting thing is that I can run this script successfully with presimulation netlist(schematic view).
But when I run the post simulation using config view, It failed.

The R0 is from analogLib for measure the current purpose, not layout devices. So, for pre sim and post sim, they see the same R0. Thanks.
In addition, when I open a new CIW, and execute the script, it works fine.
But if I do something in the CIW like edit schematic, layout, simulation, then execute the script, it possiblely happened.
