Description

       Converts VCD files to LXT2 files.

Limitations

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

Name

       vcd2lxt2 - 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.

Syntax

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