ASCII waveform file format for Virtuoso Visualization and Analysis XL?

Andy Stewart

I have some waveforms captured from a high speed scope that I'd like to display alongside spectre simulation results in "Virtuoso Visualization and Analysis XL" viewer using ADE-XL.  I'd assumed it would support some form of ASCII format such as ASCII tr0 but the Cadence docs dont list any ASCII file formats in the table of supported waveform data files.  I cant see any way of getting into sst2 or psf formats from ASCII either.  Does anyone have any ideas on how I might do this?

  • If you can get the captured waveforms into VCSV format, you'll be able to display them inside spectre. I'm not sure if there's a utility that can take tr0 and convert to VCSV but you can export a sample spectre waveform as VCSV format to see roughly how the ASCII file is organized and then try to get your captured waveform data to conform to this format by hand.

    Once you have the VCSV format, you can go to Visualization and Analysis XL and open the waveform (File -> Open Results...) and then use the trace as if it's just like any other trace from spectre.
