  21 NAME
  22        vcd2lxt2 - Converts VCD files to LXT2 files
  23
  24 SYNTAX
  25        vcd2lxt2 [option]... [VCDFILE] [LXTFILE]
  26
  27 DESCRIPTION
  28        Converts VCD files to LXT2 files.
  29
  30 OPTIONS
  31        -v,--vcdname &lt;filename&gt;
  32               Specify VCD input filename.
  33
  34        -l,--lxtname &lt;filename&gt;
  35               Specify LXT2 output filename.
  36
  37        -d,--depth &lt;value&gt;
  38               Specify 0..9 gzip compression depth, default is 4.
  39
  40        -m,--maxgranule &lt;value&gt;
  41               Specify number of granules per section, default is 8.  One gran-
  42               ule is equal to 32 timsteps.
  43
  44        -b,--break &lt;value&gt;
  45               Specify break size (default = 0 = off).  When the break size  is
  46               exceeded, the LXT2 dumper will dump all state information at the
  47               next convenient granule plus dictionary boundary.
  48
  49        -p,--partialmode &lt;mode&gt;
  50               Specify partial zip mode 0 = monolithic, 1 = separation.   Using
  51               a  value of 1 expands LXT2 filesize but provides fast access for
  52               very large traces.  Note that the default mode is neither  mono-
  53               lithic nor separation: partial zip is disabled.
  54
  55        -c,--checkpoint &lt;mode&gt;
  56               Specify  checkpoint  mode.   0  is on which is default, and 1 is
  57               off.  This is disabled when the break size is active.
  58
  59        -h,--help
  60               Show help screen.

  64        EXAMPLES
  65
  66        Note that you should specify  dumpfile.vcd  directly  or  use  &quot;-&quot;  for
  67        stdin.
  68
  69        vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --break 1073741824
  70               This  sets the compression level to 9 and sets the break size to
  71               1GB.
  72
  73        vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --maxgranule 256
  74               Allows more granules per section which allows for  greater  com-
  75               pression.
  76
  77 LIMITATIONS
  78        vcd2lxt2  does  not store glitches as these are coalesced together into
  79        one value change during the writing of the LXT2 file.
