I would run multiple AC simulations (with Spectre simulator) using an Ocean Script. However I would change for each loop the stimulus file. I don't know how to specify the changing of the name of the stimulus file for each run.
Thanks in advance for your help
simulator('spectre)design(...)analysis('ac ...)foreach(stimFile '("file1.scs" "file2.scs" "file3.scs") stimulusFile(stimFile) run() ; process the results as you wish)
Something like that?
In reply to Andrew Beckett:
In reply to lartola:
for(i 1 1000 stimulusFile(sprintf(nil "stimFile%d.scs" i)) run() ...)
Use something like sprintf() to build the filename as you go along.
i've worked on the ocean script for running multiple AC simulation as you said me.
However I get a problem. Actually the loop works perfectly but the simulator seems don't used the correct stimulus file. If I check the netlist file all of the used stimulus are present but when I check the simulated data something seems wrong.
Actually, the simulator seems add loop after loop each the stimulus files. I Need to perform a reset for each run or something like that ?
Following the current ocean script i'm using:
;------------- Initialization -------------------------------------
simulator( 'spectre )
stimulusFile( ?xlate nil "/*******/spectre/schematic/netlist/_graphical_stimuli.scs")
temp( 23.0 )
TotalRun = 3
;------------- Automatic electrical runs -------------------------
Tempfile1 = outfile( "/************net6_testpostprocess.txt" "w")
Tempfile2 = outfile( "/************net7_testpostprocess.txt" "w")
for(i 1 TotalRun
stimulusFile( ?xlate nil sprintf( nil "/*********Stimulis_test_MUSCA_SETcurrent_SRAM_%d.txt" i))
analysis('tran ?stop "0.055E-6" ?method "trap")
envOption( 'analysisOrder list("tran"))
option( 'temp "23.0" )
selectResult( 'tran )
plot(getData("/I4/A") getData("/net06") getData("/net7") getData("/WL") getData("/BLbarre") getData("/BL"))
ocnPrint( v("/net06") ?output Tempfile1 ?numberNotation 'none ?precision 15 ?width 20)
ocnPrint( v("/net7") ?output Tempfile2 ?numberNotation 'none ?precision 15 ?width 20)
Thanks in advance for your time
The problem is that each time you call stimulusFile() with a different file, it adds to the list of stimulus files. The usual way of solving this with OCEAN is to use the delete() function to reset the particular item (you can delete analyses, saves etc), but unfortunately delete('stimulusFile) hasn't been implemented yet.
This is described in my solution 1026408 on Cadence Online Support. The workaround is to use::
asiSetEnvOptionVal(asiGetCurrentSession() 'stimulusFile list(stimFile))
where stimFile is the file you want to set. This will override any previous stimulus file lists that have been set.
