VCD2LXT2(1)                   Filetype Conversion                  VCD2LXT2(1)



NAME
       vcd2lxt2 - Converts VCD files to LXT2 files

SYNTAX
       vcd2lxt2 [option]... [VCDFILE] [LXTFILE]

DESCRIPTION
       Converts VCD files to LXT2 files.

OPTIONS
       -v,--vcdname <filename>
              Specify VCD input filename.

       -l,--lxtname <filename>
              Specify LXT2 output filename.

       -d,--depth <value>
              Specify 0..9 gzip compression depth, default is 4.

       -m,--maxgranule <value>
              Specify number of granules per section, default is 8.  One
              granule is equal to 32 timsteps.

       -b,--break <value>
              Specify break size (default = 0 = off).  When the break size is
              exceeded, the LXT2 dumper will dump all state information at the
              next convenient granule plus dictionary boundary.

       -p,--partialmode <mode>
              Specify partial zip mode 0 = monolithic, 1 = separation.  Using
              a value of 1 expands LXT2 filesize but provides fast access for
              very large traces.  Note that the default mode is neither
              monolithic nor separation: partial zip is disabled.

       -c,--checkpoint <mode>
              Specify checkpoint mode.  0 is on which is default, and 1 is
              off.  This is disabled when the break size is active.

       -h,--help
              Show help screen.



       EXAMPLES

       Note that you should specify dumpfile.vcd directly or use "-" for
       stdin.

       vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --break 1073741824
              This sets the compression level to 9 and sets the break size to
              1GB.

       vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --maxgranule 256
              Allows more granules per section which allows for greater
              compression.

LIMITATIONS
       vcd2lxt2 does not store glitches as these are coalesced together into
       one value change during the writing of the LXT2 file.
