Data mining of vzt files
vztminer [option]... [VZTFILE]
Mines VZT files for specific data values and generates gtkwave save files to stdout for future reload.
-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.
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.
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.
