Reading parmetric sweep data through ocean

lahsivece

Hi All,

I have a set of parmetric sweep results generated through spectre simulation . These file names are of the format 

"sweep_variablename_-<iteration numbers>_sweep_another_variable_name-<iteration_number>_....tran.tran"

I am trying to read the file through Ocean and perform some analysis on data generated. My ocean script looks like following:

sprintf(rdir "<path_to_spectre_simulation_directory>/spectre/schematic")
openResults(strcat(rdir,"/psf")) 

; The above sets the results directory to the psf folder. All parametric sweep results are dumped there.

 

selectResult('tran)
clip_v1p=clip(v("/V1P" ?result "sweepb2_1-000_sweepb1_1-000_sweepb0_1-001_tran-tran") 010e-09 28e-09)

On executing the script  i get following error message

The output '/V1P' you selected does not exist.  Type
          outputs() to see the list of available outputs or type
          help('v) for more information on the 'v' command.


However when I execute outputs() I get the netname in the list.

What am I doing wrong ?

I can read single spectre simulation data through ocean but Can I read parametric sweep spectre simulation data through ocean ?

Please advise.

Thanks & regards

  • Vishal,

    If your sweep is like you described earlier, with nested sweeps for b0, b1 and b2, your calculations are not doing a value() on 'b2 - so you will get the frequency versus b2  in the output above. Try plotting the result and see what you get - it's quite handy to see what the waveform looks like when you're trying to understand such issues.

    Regards,

    Andrew.

  • Hi Andrew,

    Yes, it was the case. On plottting , the plot was of frequency() with respect to b2. 

    After adding value() on b2 , I do get desired output. 

    Thanks for your help

    Regards

    Vishal
