OCEAN Parametric analysis

Ueue

Dear all,

 

I am running parametric analyses with an OCEAN script.

It finishes and all the output variables are correctly evaluated.

I calculate two variables L_opt and eff_opt, that are single values, not array and I try to write them in a file.

Trying to write the data in the file OCEAN generates the following error:

" *Error* fprintf/sprintf: format spec. incompatible with data - 100000000 "

 

My script is:

"

...

fname="path/result.txt"

fileOut=outfile(fname "w")

...

paramAnalysis("L" ?start L1 ?stop L2 ?log NL)

...

paramRun()

...

; calculation of p_out and p_in ...

L_opt=xmax(p_out / (p_out + p_in) * 100)

eff_opt=value((p_out / (p_out + p_in) * 100) L_opt)

fprintf(fileOut "3.8f \t 3.8f \t \n", L_opt, eff_opt) 

 

Thanks a lot,

Stefano

  •  Hi Andrew,

     I am experiencing the same sort of problem although I am not using any special OCEAN or SKILL script. I was trying to print out a signal to a text file to use it as a PWL source later on. As the number of significant digits used by the waveform calculator is limited to about 4 (despite my having changed this number under "Options->Significant Digits"), I decided to use ocnPrint through the CI.

     I try

    ocnPrint(?output "myOut.txt" ?precision 10 ?numberNotation 'none clip( i("I0:3" ?result "tran-tran" ?resultsDir "pathname") 2n 10n) )

     Note that the expression is simply copied from the calculator buffer. I get the following error message:

     *Error* fprintf/sprintf: format spec. incompatible with data - "Format is '%g', argument #1 is 170"

    I get the same problem if I try to print a voltage, and so it is not caused by the current not being saved with the correct port mapping or so. 

    I even tried to run it by directly invoking OCEAN in the terminal, and selecting the results with openResults(), selectResults() etc., but to no avail. I don't get an error message there, just an empty output file. Of course, when I run OCEAN in the terminal, I leave out the ?result and ?resultsDir parts, since they have been already taken care of with openResults() and selectResults().

     I am working with Cadence IC 6.1.4.

    Thanks,

    Vivek
