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.
