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 gran-
ule 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 mono-
lithic 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 com-
pression.
LIMITATIONS
vcd2lxt2 does not store glitches as these are coalesced together into
one value change during the writing of the LXT2 file.
