i use paramAnalysis and how to get the output?

imagesensor123

 Hi ,

    I use paramAnalysis in my ocean to do a parametric analysis, and now i want to get the output of every sweep value at the certain time . for example, i used the paramAnalysis( "lin" ?start 10u ?stop 50u ?step 10u) to do a transient simulation for 100us , now how can i get the vout value for lin=10 time=50us and lin=20u time=50u ,and so on.In addition , i found that the command "value" can get the signal value at the specified time,like value(v("vout") 50u), but how can i get the value "vout lin=20 time=50us" ? thanks

Regrads,

     Indeed, the sweepNames() function returns "case" "tsh" "time".

    I can even autoplot the individual cases/corners.  I just can't seem to wrok on the data.  Here's a snapshot ..{fout is a declared and opened file handle with the 'w' option}

    paramAnalysis("case" ?values '(0 1)

    paramAnalysis("tsh" ?values '(-5e-10 -4e-10)

    ))

    resultsDir("./psf1")

    paramRun()

    openResults("./psf1")

    selectResults('tran)

    tf=cross(v("Vout") 1 3 'falling)

    ocnPrint(?output fout tf)

    close(fp)

     ...........................END

    Fingers crossed I've copied all the brackets across carefully.  If I ocnPrint v("Vout"), then I it prints the Vout vs time for both case 0 and 1.  If I change the desVar( "case" 0) to desVar( "Case" 0), then the above code prints both cases, but such a variable doesn't exist so the corner never moves from nominal.

     

    I think I may go back to basics and try a nested 'foreach' loop.  I read that paramAnalysis() is quicker to implement and easier, but I can't figure out why it has a problem with 'case'.

    Cheers Man!
