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

NAME
vztminer - Data mining of VZT files SYNTAX
vztminer [option]... [VZTFILE] DESCRIPTION
Mines VZT files for specific data values and generates gtkwave save files to stdout for future reload. OPTIONS
-d,--dumpfile <filename> Specify VZT input dumpfile. -m,--match <value> Specifies "bitwise" match data (binary, real, string) -x,--hex <value> Specifies hexadecimal match data that will automatically be converted to binary for searches -n,--namesonly Indicates that only facnames should be printed in a gtkwave savefile compatible format. By doing this, the file can be used to specify which traces are to be imported into gtkwave. -c,--comprehensive Indicates that results are not to stop after the first match. This can be used to extract all the matching values in the trace. -h,--help Show help screen. EXAMPLES
vztminer dumpfile.vzt --hex 20470000 -n This attempts to match the hex value 20470000 across all facilities and when the value is encountered, the facname only is printed to std- out in order to generate a gtkwave compatible save file. LIMITATIONS
vztminer only prints the first time a value is encountered for a specific net. This is done in order to cut down on the size of output files and to aid in following data such as addresses through a simulation model. Note also that the reader algorithm attempts to recon- struct bitblasted nets back into their original vectors but this is not always successful, specifically in the case where the individual bitstrands are dumped in non-sequential order.
