ocean script - corner list

jugemu1234

Hi there,

 When I plan to run several specific corner simulations as in following,

 

myCorner0='(tt,-40,1.5)

myCorner1= '(tt,125,1.4)

myCorner2= '(ff,-40,1.6)

 

I noticed "foreach" structure is sort of redundant way because obviously not necessary corners will be included much.

foreach(myMOS '("tt" "ff")

foreach(myTemp '("-40" "125")

foreach(myVdd '("1.4" "1.5" "1.6")

;;;code here

)))

 

So could you anybody suggest me how to construct efficient ocean script code? 

 

Thanks in advance.

    How to run parametric analysis over corners using Ocean in IC5141?

    soldiv { word-wrap: break-word; overflow: hidden; }soldiv p { margin-left: 0px; }.solDiv blockquote { margin-left: 25px; }soldefault { font-size: 12pt; }.solDefault font { font-size: 12pt; }
    Error Message

    Nil

    Problem

    You would like to run a parametric analysis over a corners. Say you have model corners "typtyp", "fastfast" and "slowslow". You would like to run a parametric analysis on all these corners. How to do run this using Ocean script?

    Solution

    You can use the following Ocean script to run a parametric analysis over a set of corners.

     

    ;;; Start of Script

    ocnWaveformTool( 'wavescan )

    simulator( 'spectre )

    design("/home/user/simulation/ampTest/spectre/schematic/netlist/netlist")

    desVar( "vsup"  3.3 )

    myCors = list("typtyp" "fastfast" "slowslow")  ;;; Available corners

     

    foreach(myModelSec myCors

     

    myResultsDir = strcat("/home/user/simulation/ampTest/spectre/schematic/" myModelSec)

    resultsDir(myResultsDir)

    modelFile(

    '("/home/user/dummy.scs" "")

    list("/home/user/mySingle.scs" myModelSec)

      )

     

    analysis('tran ?stop "1u")

    temp( 27 )

    paramAnalysis("temp" ?values '(20 25 30)

    )

    paramRun()

    );;; End of Script

     

     

    The above script runs parametric analysis sweeping the variable "temp" for all the corners specified (typtyp, fastfast and slowslow). A total of 9 simulations will be run for the above example. The simulation output directory (psf) will be created with a unique name for all 9 runs reflecting the corner and sweep value. For this case, an example would be,

     

    /home/user/simulation/ampTest/spectre/schematic/fastfast/temp=25
