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.
