Printing to file after running Parametric Analysis

mk123

Hi, 

I am running an ocean script to do a parametric analyis. The parameters are VDD and temperature and analysis is transient. The script goes something like the following,

 paramAnalysis("VDD" ?values (3 5)

paramAnalysis("temp" ?values(-40 125)

)

)

paramRun()

openResults(dir)

selectResults('tran)

outputs()

avg=average(VT("/net1"))

out=outfile("filename" "a")

;fprintf( out "VDD=%d Temp=%d Average=%g" VDD temp avg)

 fprintf( out "Average=%g" avg)

close(out)

 

What I want to do is print the results in a flie for each value specified by the parametric analysis. There are two problems,

(1) If I run the commented "fprintf" line in the code above,  VDD and temp are not variables anymore. So I get the error as "unbound variables" as expected. Is there a way to print these values ???

 (2) For the second fprintf line, asI am running a parametric analysis, all the transient runs are done alreayd. Thus, the variable average is now a graph.Therefore the printed value is now "drwave:123456". Is there a way to print each of this value corresponding to each VDD and temp??

 I have tried using "foreach ", instead of running a parametric analysis and that works when I want to print into file. However, I found that parametric analysis was faster.

 

Thanks,

Mandar

  • Hi Mandar,

    If you opened the result file in append mode (which your code used), then you absolutely should be able to use ?output out and it should append.

    If this isn't working for you, I'd suggest contacting Cadence Customer Support - maybe there's a real problem there that needs to be solved.

    Regards,

    Andrew.
