This is the command vcd2vzt that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
vcd2vzt - Converts VCD files to VZT files
SYNTAX
vcd2vzt [option]... [VCDFILE] [VZTFILE]
DESCRIPTION
Converts VCD files to VZT files.
OPTIONS
-v,--vcdname <filename>
Specify VCD input filename.
-l,--vztname <filename>
Specify VZT 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
timesteps.
-b,--break <value>
Specify break size (default = 0 = off). When the break size is exceeded, the VZT
dumper will dump all state information at the next convenient granule plus
dictionary boundary.
-z,--ziptype <value>
Specify zip type (default = 0 gzip, 1 = bzip2, 2 = lzma). This allows you to
override the default compression algorithm to use a more effective one at the
expense of greater runtime. Note that bzip2 does not decompress as fast as gzip so
the viewer will be about two times slower when decompressing blocks.
-t,--twostate
Forces MVL2 twostate mode (default is MVL4). When enabled, the trace will only
store 0/1 values for binary facilities. This is useful for functional simulation
and will speed up dumping as well as make traces somewhat smaller.
-r, --rle
Uses an bitwise RLE compression on the value table. Default is off. When enabled,
this causes the trace data table to be stored using an alternate representation
which can improve compression in many cases.
-h,--help
Show help screen.
EXAMPLES
Note that you should specify dumpfile.vcd directly or use "-" for stdin.
vcd2vzt dumpfile.vcd dumpfile.lxt --depth 9 --break 1073741824
This sets the compression level to 9 and sets the break size to 1GB.
vcd2vzt dumpfile.vcd dumpfile.lxt --depth 9 --maxgranule 512
Allows more granules per section which allows for greater compression at the
expense of memory usage.
LIMITATIONS
vcd2vzt does not store glitches as these are coalesced together into one value change
during the writing of the VZT file.
