Eldo Conversion Utilities
Utility to Convert a Waveform Database
Table D-1. ffcv Output Format Modifier (cont.)
output_format_modifier Output Format
-tabular
Tabulated representation of waveforms
-wdf WDF file, compatible version is v2007.1
• output_database
Output filename. Name of the waveform database file to write converted format to. By
default the root name of the input file is used with the output format modifier extension.
General Purpose Arguments
• -cvt_start xstart
Conversion start point (time or frequency) in database.
• -cvt_stop xstop
Conversion end point (time or frequency) in database.
• -cvt_tsample xvalue
Time or frequency interval to sample output data.
• -cvt_progress
Displays the conversion progression, in percent.
• -cvt_duplicate_rule FIRST | MAX | MIN | LAST | ALL
Selects which value must be written to the output database when the input database contains
multiple values at the same X. Default is set to ALL if the input database uses a compatible
format, and MAX for other formats.
Format-Specific Arguments
• -cvt_mode SEQUENTIAL | GROUP | FULL
Applies to FSDB format only. Selects the method used to convert the input database into the
target format(s). This option is format dependent: it can be ignored if the input (or output)
format does not support one or the other method. Default is set to FULL.
FULL
All waveforms are loaded in a single pass reading. This method is faster than the
sequential method, but it requires more memory. Default.
GROUP
Waveforms are loaded in groupings of 200. This is an intermediate conversion mode
between FULL and SEQUENTIAL. To modify the grouping size specify argument
-cvt_group_size.
SEQUENTIAL
Waveforms are loaded one after another. This method is often slower because it uses
multiple-pass reading. However, it usually requires less memory.
