LXT2VCD(1)							Filetype Conversion							LXT2VCD(1)

NAME
lxt2vcd - Converts LXT2 files to VCD SYNTAX
lxt2vcd [option]... [LXT2FILE] DESCRIPTION
Converts LXT2 files to VCD files on stdout. Note that "regular" LXT2 files will convert to VCD files with monotonically increasing time values. LXT2 files which are dumped with the "partial" option (to speed up access in wave viewers) will dump with monotonically increasing time values per 2k block of nets. This may be fixed in later versions of lxt2vcd. OPTIONS
-l,--lxtname <filename> Specify LXT2 input filename. -f,--flatearth Emit flattened hierarchies. -n,--notruncate Do not shorten bitvectors. This disables binary value compression as described in the IEEE-1364 specification. (i.e., all values except for '1' left propagate as a sign bit on vectors which do not fill up their entire declared width) -h,--help Display help then exit. EXAMPLES
To run this program the standard way type: lxt2vcd filename.lxt The VCD conversion is emitted to stdout. LIMITATIONS
lxt2vcd does not re-create glitches as these are coalesced together into one value change during the writing of the LXT2 file. AUTHORS

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. AUTHORS
