Simulation from an imported CSV file

JB202507023247

Hello Sir,

I was wondering if there's a tutorial or something for a way to simulate and get graphs of a CSV file of voltage over time imported to cadence ? 

I tried vpwlf and vpwlfm but both don't work.

Error CMI 3035 syntax in waveform file .

Ensure that the time values are entered in pairs w each pair specified in separate line.

But already the CSV has only one column for time 

Thank you 

  • Hi,

    Do you want to view the signal defined in .csv, or use this signal to drive a circuit in Spectre?

    You can try loading this .csv into ViVA and see if you get the expected waveform. From ViVA, you can also export out a 'VCSV' format file (click on the trace -> Send to -> Export). This file can be used with vpwlf source in Spectre.

    Regards,

    Saloni
