NAME
gtkwave - Visualization tool for VCD, LXT, and VZT files
SYNTAX
gtkwave [option]... [DUMPFILE] [SAVEFILE] [RCFILE]
DESCRIPTION
Visualization tool for VCD, LXT, LXT2, and VZT. VCD is an industry
standard simulation dump format. LXT, LXT2, and VZT have been designed
specifically for use with gtkwave. Native dumpers exist in Icarus Ver-
ilog for the LXT formats so conversion with vcd2lxt(1) or vcd2lxt2(1)
is not necessary to take direct advantage of LXT with that simulator.
AET2 files can also be processed provided that libae2rw is available
but this is only of interest to people who use IBM EDA toolsets.
OPTIONS
-n,--nocli <directory name>
Use file requester for dumpfile name
-f,--dump <filename>
Specify dumpfile name.
-r,--rcfile <filename>
Specify override .gtkwaverc filename.
-i,--indirect <filename>
Specify indirect facs file name. The file contains a series of
regular expressions used to limit what signals can be browsed.
Signal names which match any of the regular expressions will be
viewable. Typically, indirect files are used to reduce memory
requirements for extremely large models containing millions of
facilities or to strip out top-level hierarchy clutter from
BugSpray models. This feature is only available with the AET2
loader.
-l,--logfile <filename>
Specify simulation logfile name. Multiple logfiles may be spec-
ified by preceeding each with the command flag. By selecting
the numbers in the text widget, the marker will immediately zoom
to the specific time value.
-d,--defaultskip
If there is not a .gtkwaverc file in the home directory or cur-
rent directory and it is not explicitly specified on the command
line, when this option is enabled, do not use an implicit con-
figuration file and instead default to the old "whitescreen"
behavior.
-s,--start <time>
Specify start time for LXT2/VZT block skip.
-e,--end <time>
Specify end time for LXT2/VZT block skip.
-c,--cpu <numcpus>
Specify number of CPUs available for parallelizable ops (e.g.,
block prefetching on VZT reads).
-v,--vcd
Use stdin as a VCD dumpfile.
-V,--version
Display version banner then exit.
-h,--help
Display help then exit.
-x,--exit
Exit after loading trace (for loader benchmarking).
FILES
~/.gtkwaverc
EXAMPLES
To run this program the standard way type:
gtkwave dumpfile.vcd
Alternatively you can run it with a save file as:
gtkwave dumpfile.vcd dumpfile.sav
Command line options are not necessary for representing the dumpfile,
savefile, and rcfile names. They are merely provided to allow specify-
ing them out of order. Note that on non-glibc systems, the long com-
mand line options will not be available and that the short ones will
have to be used instead.
