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 stdout 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
reconstruct 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.
