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?

  • In the ViVA calculator, there's also the "getAsciiWave" function which will read simple multi-column data and convert it into waveforms.

    As suggested above, the VCSV format is relatively straightforward; it's comma-separated-value with some additional header information in comments at the top of the file to give information about signal names, type of data, and so on - it provides more info for ViVA to know how to plot the data.

    There is also the "psf" utility to convert psf format data from ASCII to binary. However, constructing a file that looks like ASCII PSF is going to be a lot more work than using VCSV.

    We also have an enhancement request to be able to directly open simple CSV files in ViVA - but it's not been implemented yet (it would need some kind of import UI to assign signals to columns, a bit like you get when you import a text file in Excel).

    Best Regards,

    Andrew.
