gtkwave - Visualization tool for VCD, LXT, and VZT files
gtkwave [option]... [DUMPFILE] [SAVEFILE] [RCFILE]
Visualization tool for VCD, LXT, LXT2, VZT, and GHW. VCD is an
industry standard simulation dump format. LXT, LXT2, and VZT have been
designed specifically for use with gtkwave. GHW is the native VHDL
format generated by GHDL. Native dumpers exist in Icarus Verilog and
the open source version of VeriWell for the LXT formats so conversion
with vcd2lxt(1) or vcd2lxt2(1) is not necessary to take direct
advantage of LXT with those simulators. AET2 files can also be
processed provided that libae2rw is available but this is only of
interest to people who use IBM EDA toolsets.
-n,--nocli <directory name>
Use file requester for dumpfile name.
Specify dumpfile name.
optimize VCD to LXT2. This will automatically call vcd2lxt2(1)
to perform the file conversion. This option is highly
recommended with large VCD files in order to cut down on the
memory usage required for file viewing. Can be used in
conjunction with -v,--vcd.
Specify override .gtkwaverc 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
Specify simulation logfile name. Multiple logfiles may be
specified 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.
If there is not a .gtkwaverc file in the home directory or
current directory and it is not explicitly specified on the
command line, when this option is enabled, do not use an
implicit configuration file and instead default to the old
Specify multisession identifier information. The format of
"which" is m+nnnnnnnn where m is the session number 0 or 1 and
nnnnnnnn is a hexadecimal value indicating the shared memory ID
of an array of two gtkwave_dual_ipc_t data structures. The
intended use of this flag is for front ends such as twinwave(1).
Specify start time for LXT2/VZT block skip.
Specify end time for LXT2/VZT block skip.
Specify stems file for source code annotation. This will
automatically launch the rtlbrowse(1) helper process. See
vermin(1) for information on stems file generation.
Specify number of CPUs available for parallelizable ops (e.g.,
block prefetching on VZT reads).
Disable window manager for most windows. The intended use of
this is to be used in conjunction with the --script option,
however this also can be used to reparent into an alternate
Do not render menubar. This is mainly used for making a
restricted applet that cannot initiate file I/O on its own,
however it also can be used as a workaround in earlier versions
of GTK+ that do not handle GTKSocket/GTKPlug focus interactions
Specify GUI command script file for execution. Comments are
indicated by the ’#’ character. Lines in the script are the
full menu pathname including the first forward slash. Arguments
for an option (such as a filename) will follow with one argument
each on its own separate line. Menu options that bring up
complex requesters (e.g., search) will hang in the GUI waiting
for user intervention. The intended use of this option is to
allow automated subset extraction to VCD as well as automated
Postscript file generation. If the script filename is suffixed
with .tcl, then the script will be considered to be Tcl.
Specify Tcl command script for periodic execution.
Specifies delay in milliseconds between successive executions of
the repscript. Default is 500.
Specify XID of window for a GtkPlug to connect to. GTKWave does
not directly render to a window but instead renders into a
GtkPlug expecting a GtkSocket at the other end. Note that there
are issues with accelerators working properly so menus are
disabled in the componentized version of GTKWave when it
functions as a plug-in.
Specifies that "interactive" VCD mode is to be used which allows
a viewer to navigate a VCD trace while GTKWave is processing the
VCD file. When this option is used, the filename is overloaded
such that it is the hexadecimal value for the shared memory ID
of a writer. Note that the shared memory ID can be passed
straight from stdin by using the --vcd option; see the manpage
for shmidcat(1) for more details.
Specifies that the viewer should use legacy VCD mode rather than
the VCD recoder. Note that using legacy mode will require
considerably more memory than the recoder and its use is
discouraged for very large traces.
Specifies that the viewer should use gigabyte mempacking when
recoding (possibly slower). This is equivalent to setting the
vlist_spill and vlist_prepack flags in the rc file.
Specifies that the viewer should use compressed hierarchy names
when loading the dumpfile (available for VCD recoder, LXT, LXT2,
and VZT). This will use less memory at the expense of
Use stdin as a VCD dumpfile.
Specify filename for stdout/stderr redirect. To disable
messages to the console, use /dev/null as the filename.
Display version banner then exit.
Display help then exit.
Exit after loading trace (for loader benchmarking).
~/.gtkwaverc (see manpage gtkwaverc(5))
To run this program the standard way type:
Alternatively you can run it with a save file as:
gtkwave dumpfile.vcd dumpfile.sav
To run interactively using shared memory handle 0x00050003:
gtkwave -I 00050003 dumpfile.sav
Note that to pass non-flag items which start with a dash, that it is
required to specify -- in order to turn off flag parsing. A second --
will disable parsing of any following arguments such that they can be
passed on to Tcl scripts and retrieved via gtkwave::getArgv.
Command line options are not necessary for representing the dumpfile,
savefile, and rcfile names. They are merely provided to allow
specifying them out of order.
AIX requires -bmaxdata:0x80000000 (-bmaxdata:0xd0000000/dsa for AIX
5.3) to be added to your list of compiler flags for xlc if you want
GTKWave to be able to access more than 256MB of virtual memory. The
value shown allows the VMM to use up to 2GB (3.25GB AIX5.3). This may
be necessary for very large traces.
Shift and Page operations using the wave window hscrollbar may be
nonfunctional as you move away from the dump start for very large
traces. A trace that goes out to 45 billion ticks has been known to
exhibit this problem. This stems from using the gfloat element of the
horizontal slider to encode the time value for the left margin. The
result is a loss of precision for very large values. Use the hotkeys or
buttons at the top of the screen if this is a problem.
When running under Cygwin, it is required to enable Cygserver if shared
memory IPC is being used. Specifically, this occurs when rtlbrowse(1)
is launched as a helper process. See the Cygwin documentation for more
information on how to enable Cygserver.
