NAME

       gtkwaverc - GTKWave Configuration File

SYNTAX

       option <value>

       The  configuration  file is a series of option and value pairs.  Comment lines marked with
       an initial '#' character are permissible.  Blank lines are ignored.

DESCRIPTION

       Configuration file for gtkwave(1).   The  search  path  for  the  configuration  file  (if
       unspecified) is the current working directory followed by the user's home directory.

OPTIONS

       accel <"pathvalue" accelerator>
              This  allows  replacement of menu accelerator keys.  See the .gtkwaverc file in the
              source distribution for examples on pathvalue and accelerator syntax.  The  special
              accelerator value of (null) means that no accelerator is bound to the menu item.

       alt_hier_delimeter <value>
              This  allows  another  character  in  addition  to the hier_delimeter to be used to
              delimit levels in the hierarchy for VCD. Only the first character in the  value  is
              significant.  Note  that  this  is normally off. The intended use is to resolve the
              hierarchies of netlist based models that often contain slashes to delimit hierarchy
              inside of $var statements.

       alt_wheel_mode <value>
              Default is on.  Scrollwheel alone pans along a quarter at a time rather than a full
              page, so you don't get lost.  Ctrl+wheel  zooms  in/out  around  the  mouse  cursor
              position,  not  the  marker  position.   Alt+wheel  edges  left/right  based on the
              currently selected signal.  This makes measuring deltas easier.

       analog_redraw_skip_count <value>
              Specifies how many overlapping analog segments can be drawn for a given X  position
              onscreen.   (Default:  20)   If  there are gaps in analog traces, this value is too
              low.

       append_vcd_hier <value>
              Allows the specification of a prefix hierarchy for VCD files. This can be  done  in
              "pieces,"  so  that multiple layers of hierarchy are prepended to symbol names with
              the most significant addition occurring first (see .gtkwaverc in the   examples/vcd
              directory).  The  intended  use  of  this  is  to have the ability to add "project"
              prefixes which allow easier selection of everything from the tree hierarchy.

       atomic_vectors <value>
              Speeds up vcd loading and takes up less memory. This option is  deprecated;  it  is
              currently the default.

       autocoalesce <value>
              A  nonzero value enables autocoalescing of VCD vectors when applicable. This may be
              toggled dynamically during wave viewer usage.

       autocoalesce_reversal <value>
              causes split vectors to be reconstructed in reverse order (only if autocoalesce  is
              also active).

       autoname_bundles <value>
              A nonzero value indicates that GTKWave will create its own bundle names rather than
              prompting the user for them.

       clipboard_mouseover <value>
              A nonzero value indicates that when mouseover is enabled, all values generated  for
              the  tooltips will be automatically copied into the clipboard so they may be pasted
              into other programs such as text editors, etc.

       color_0 <value>
              trace color when 0.

              for highlight_wavewindow when enabled.

       color_grid2 <value>
              grid color for secondary pattern search.

       color_high <value>
              trace color when high ("H").

              trace color when undefined ("U").

       color_ufill <value>
              trace color (inside of box) when undefined ("U").

       color_umark <value>
              color of the unnamed (primary) marker.

       color_value <value>
              text color for vector values.

       color_vbox <value>
              vector color (horizontal).

       color_vtrans <value>
              vector color (verticals/transitions).

       color_w <value>
              trace color when weak ("W").

       color_wfill <value>
              trace color (inside of box) when weak ("W").

       color_white <value>
              color value for "white" in signal window.

       color_x <value>
              trace color when undefined ("X") (collision for VHDL).

       color_xfill <value>
              trace color (inside of box) when undefined ("X") (collision for VHDL).

       constant_marker_update <value>
              A  nonzero  value  indicates that the values for traces listed in the signal window
              are to be updated constantly when the left mouse button is being held  down  rather
              than only when it is first pressed then when released (which is the default).

       context_tabposition <value>
              Use zero for tabbed viewing with named tabs at the top.  Nonzero places numerically
              indexed tabs at the left.

       convert_to_reals <value>
              Converts all integer and parameter VCD declarations to real-valued ones when set to
              a  nonzero/yes  value.  The positive aspect of this is that integers and parameters
              will take up less space in memory and will automatically display in decimal format.
              The  negative  aspect  of  this  is  that  integers  and  parameters  will  only be
              displayable as decimals and can't be bit reversed, inverted, etc.

       cursor_snap <value>
              A nonzero value indicates the number of pixels the marker should snap  to  for  the
              nearest signal transition.

       disable_ae2_alias <value>
              A  nonzero value indicates that the AE2 loader is to ignore the aliasdb keyword and
              is not to construct facility aliases.

       disable_auto_comphier <value>
              A nonzero value indicates that the  loaders  that  support  compressed  hierarchies
              should  not  automatically  turn  on  compression if the threshold count of signals
              (500000) has been reached.

       disable_empty_gui <value>
              A nonzero value indicates that if gtkwave is invoked without a dumpfile name,  then
              an empty gtkwave session is to be suppressed.  Default is a zero value: to bring up
              an empty session which needs a file loaded or dragged into it.

       disable_mouseover <value>
              A nonzero value indicates that signal/value tooltip pop up bubbles on mouse  button
              presses  should  be disabled in the value window. A zero value indicates that value
              tooltips should be active (default is disabled).

       disable_tooltips <value>
              A nonzero value indicates that tooltip pop up bubbles should be  disabled.  A  zero
              value indicates that tooltips should be active (default).

       do_initial_zoom_fit <value>
              A  nonzero  value  indicates that the trace should initially be crunched to fit the
              screen. A zero value indicates that the initial zoom should be zero (default).

       dragzoom_threshold <value>
              A nonzero value indicates the number of pixels in the x direction the  marker  must
              move  in  order  for  a  dragzoom to be triggered.  This is largely to handle noisy
              input devices.

       dynamic_resizing <value>
              A nonzero value  indicates  that  dynamic  resizing  should  be  initially  enabled
              (default).  A  zero  value  indicates  that  dynamic  resizing  should be initially
              disabled.

       editor <"value">
              This is used to specify a string (quotes mandatory) for when gtkwave invokes a text
              editor  (e.g.,  Open  Source  Definition).   Examples are: editor "vimx -g +%d %s",
              editor "gedit +%d %s", editor "emacs +%d %s", and for OSX, editor "mate -l %d  %s".
              The  %d  may  be combined with other characters in a string such as +, etc.  The %s
              argument must stand by itself.  Note that if this rc variable is not set, then  the
              environment variable GTKWAVE_EDITOR will be consulted next, then finally gedit will
              be used (if found).

       enable_fast_exit <value>
              Allows  exit  without  bringing  up  a  confirmation  requester.  The  default   is
              nonzero/yes.

       enable_ghost_marker <value>
              lets  the user turn on/off the ghost marker during primary marker dragging. Default
              is enabled.

       enable_horiz_grid <value>
              A nonzero value indicates that when grid drawing is enabled, horizontal  lines  are
              to be drawn. This is the default.

       enable_vcd_autosave <value>
              causes  the vcd loader to automatically generate a .sav file (vcd_autosave.sav ) in
              the cwd if a save file is not specified on the command line. Note that this mirrors
              the  VCD  $var  defs  and  no  attempt  is  made  to coalesce split bitvectors back
              together.

       enable_vert_grid <value>
              A nonzero value indicates that when grid drawing is enabled, vertical lines are  to
              be   drawn.   This   is  the  default.  Note  that  all  possible  combinations  of
              enable_horiz_grid and enable_vert_grid values are acceptable.

       fill_waveform <value>
              A zero value indicates that the waveform should not be filled for 1/H values.  This
              is the default.

       fontname_logfile <value>
              When followed by an argument, this indicates the name of the X11 font that you wish
              to use for the logfile browser. You may generate appropriate  fontnames  using  the
              xfontsel program.

       fontname_signals <value>
              When followed by an argument, this indicates the name of the X11 font that you wish
              to use for signals. You may  generate  appropriate  fontnames  using  the  xfontsel
              program.

       fontname_waves <value>
              When followed by an argument, this indicates the name of the X11 font that you wish
              to use for waves.  You  may  generate  appropriate  fontnames  using  the  xfontsel
              program.  Note that the signal font must be taller than the wave font or the viewer
              will complain then terminate.

       force_toolbars <value>
              When enabled, this forces everything above  the  signal  and  wave  windows  to  be
              rendered  as  toolbars.  This  allows for them to be detached which allows for more
              usable wave viewer space. By default this is off.

       hide_sst <value>
              Hides the Signal Search Tree widget for GTK2.4 and greater  such  that  it  is  not
              embedded  into the main viewer window.  It is still reachable as an external widget
              through the menus.

       hier_delimeter <value>
              This allows characters other  than  '/'  to  be  used  to  delimit  levels  in  the
              hierarchy. Only the first character in the value is significant.

       hier_grouping <value>
              For  the  tree widgets, this allows the hierarchies to be grouped in a single place
              rather than spread among the netnames.

       hier_ignore_escapes <value>
              A nonzero value indicates that the signal pane ignores escapes in identifiers  when
              determining  the  hierarchy maximum depth.  Default is disabled so that escapes are
              examined.

       hier_max_level <value>
              Sets the maximum hierarchy depth (from the right side) to display for trace  names.
              Note that a value of zero displays the full hierarchy name.

       highlight_wavewindow <value>
              When  enabled,  this  causes  traces  highlighted  in  the signal window also to be
              highlighted in the wave window.

       hpane_pack <value>
              A nonzero value indicates that the horizontal pane should be constructed using  the
              gtk_paned_pack  functions  (default  and  recommended). A zero value indicates that
              gtk_paned_add will be used instead.

       ignore_savefile_pane_pos <value>
              If nonzero, specifies that the pane position attributes (i.e., signal window  width
              size, SST is expanded, etc.) are to be ignored during savefile loading and is to be
              skipped during saving.  Default is that the attribute is used.

       ignore_savefile_pos <value>
              If nonzero, specifies that the window position attribute is to  be  ignored  during
              savefile  loading and is to be skipped during saving.  Default is that the position
              attribute is used.

       ignore_savefile_size <value>
              If nonzero, specifies that the window  size  attribute  is  to  be  ignored  during
              savefile  loading  and  is  to  be skipped during saving.  Default is that the size
              attribute is used.

       initial_signal_window_width <value>
              Sets the creation width for the signal  pane  on  GUI  initialization.   Also  sets
              another potential minimum value for dynamic resizing.

       initial_window_x <value>
              Sets  the  size of the initial width of the wave viewer window. Values less than or
              equal to zero will set the initial width equal to -1 which will let  GTK  determine
              the minimum size.

       initial_window_xpos <value>
              Sets  the  size  of the initial x coordinate of the wave viewer window. -1 will let
              the window manager determine the position.

       initial_window_y <value>
              Sets the size of the initial height of the wave viewer window. Values less than  or
              equal  to  zero will set the initial width equal to -1 which will let GTK determine
              the minimum size.

       initial_window_ypos <value>
              Sets the size of the initial y coordinate of the wave viewer window.  -1  will  let
              the window manager determine the position.

       keep_xz_colors <value>
              When nonzero, indicates that the original color scheme for non 0/1 signal values is
              to be used when Color Format overrides are in effect.  Default is off.

       left_justify_sigs <value>
              When nonzero, indicates that the signal window  signal  name  justification  should
              default to left, else the justification is to the right (default).

       lxt_clock_compress_to_z <value>
              For   LXT   (not   LXT2)  allows  clocks  to  compress  to  a  'z'  value  so  that
              regular/periodic value changes may be noted.

       max_fsdb_trees <value>
              sets the maximum number of hierarchy and signal trees to process for an FSDB  file.
              Default  =  0  =  unlimited.  The intent of this is to work around sim environments
              that accidentally call fsdbDumpVars multiple times.

       page_divisor <value>
              Sets the scroll amount for page left and right operations. (The  buttons,  not  the
              hscrollbar.) Values over 1.0 are taken as 1/x and values equal to and less than 1.0
              are taken literally. (i.e., 2 gives a half-page scroll  and  .67  gives  2/3).  The
              default is 1.0.

       ps_maxveclen <value>
              sets the maximum number of characters that can be printed for a value in the signal
              window portion of a postscript file (not including  the  net  name  itself).  Legal
              values are 4 through 66 (default).

       ruler_origin <value>
              sets the zero origin for alternate time tick marks.

       ruler_step <value>
              sets  the  left/right step value for the alternate time tick marks from the origin.
              When this value is zero, alternate time tick marks are disabled.

       scale_to_time_dimension <value>
              The value can be any of the characters m, u, n, f, p, or s, which  indicates  which
              time dimension to convert the time values to. The default for this is * which means
              that time dimension conversion is disabled.

       show_base_symbols <value>
              A nonzero value (default) indicates that the numeric base symbols  for  hexadecimal
              ('$'),  binary  ('%'),  and  octal ('#') should be rendered. Otherwise they will be
              omitted.

       show_grid <value>
              A nonzero value (default) indicates that a grid should be drawn behind the  traces.
              A zero indicates that no grid should be drawn.

       splash_disable <value>
              Turning  this  off enables the splash screen with the GTKWave mascot when loading a
              trace. Default is on.

       sst_dbl_action_type <value>
              Allows double-clicking to be active in the SST  signals  pane  with  the  following
              actions  possible:  insert  (default),  replace,  append, prepend, none.  The value
              specified for the action is case insensitive and only the first letter is required.
              Invalid action types default to none.

       sst_dynamic_filter <value>
              When  true  (default)  allows  the SST dialog signal filter to filter signals while
              keys are being pressed, otherwise enter must be pressed to cause the filter  to  go
              active.

       sst_expanded <value>
              When true allows the SST dialog (when not hidden) to come up already expanded.

       strace_repeat_count <value>
              Determines  how  many  times  that edge search and pattern search will iterate on a
              search.  This allows, for example, skipping ahead 10 clock edges instead of 1.

       use_big_fonts <value>
              A nonzero value indicates that any text rendered into  the  wave  window  will  use
              fonts  that  are  four  points  larger  in  size  than  normal.  This  can  enhance
              readability. A zero value indicates that normal font sizes should be used.

       use_frequency_delta <value>
              allows you to switch between the delta time and  frequency  display  in  the  upper
              right  corner of the main window when measuring distances between markers.  Default
              behavior is that the delta time is displayed (off).

       use_full_precision <value>
              does not round time values when the number of ticks per pixel onscreen  is  greater
              than 10 when active. The default is that this feature is disabled.

       use_maxtime_display <value>
              A  nonzero  value  indicates  that  the maximum time will be displayed in the upper
              right corner of the screen. Otherwise, the current primary  (unnamed)  marker  time
              will  be displayed. This can be toggled at any time with the Toggle Max-Marker menu
              option.

       use_nonprop_fonts <value>
              Allows accelerated redraws of the signalwindow that can be done  because  the  font
              width is constant. Default is off.

       use_pango_fonts <value>
              Uses anti-aliased pango fonts (GTK2) rather than bitmapped X11 ones. Default is on.

       use_roundcaps <value>
              A  nonzero  value  indicates  that  vector traces should be drawn with rounded caps
              rather than perpendicular ones. The default for this is zero.

       use_scrollbar_only <value>
              A nonzero value indicates that the page, shift, fetch, and discard  buttons  should
              not  be drawn (i.e., time manipulations should be through the scrollbar only rather
              than front panel buttons). The default for this is zero.

       use_scrollwheel_as_y <value>
              A nonzero value indicates that the scroll wheel on the  mouse  should  be  used  to
              scroll  the  signals  up and down rather than scrolling the time value from left to
              right.

       use_standard_clicking <value>
              This option no longer has any effect in gtkwave: normal  GTK  click  semantics  are
              used in the signalwindow.

       use_standard_trace_select <value>
              A  nonzero  value  keeps  the  currently  selected traces from deselecting on mouse
              button press. This allows drag  and  drop  to  function  more  smoothly.   As  this
              behavior is not how GTK normally functions, it is by default disabled.

       use_toolbutton_interface <value>
              A  nonzero  value indicates that a toolbar with buttons should be at the top of the
              screen instead of the traditional style gtkwave button groups.  Default is on.

       vcd_explicit_zero_subscripts <value>
              indicates that signal names should be  stored  internally  as  name.bitnumber  when
              enabled.  When  disabled, a more "normal" ordering of name[bitnumber] is used. Note
              that when disabled, the Bundle Up and Bundle  Down  options  are  disabled  in  the
              Signal  Search  Regexp,   Signal  Search Hierarchy, and Signal Search Tree options.
              This is necessary as the internal data structures for signals are represented  with
              one  "less" level of hierarchy than when enabled and those functions would not work
              properly. This should not be an issue if atomic_vectors are  enabled.  Default  for
              vcd_explicit_zero_subscripts is disabled.

       vcd_preserve_glitches <value>
              indicates  that any repeat equal values for a net spanning different time values in
              the VCD/FST file are not to be compressed into a single  value  change  but  should
              remain  in  order  to  allow  glitches  to  be  present  for this case. Default for
              vcd_preserve_glitches is disabled.

       vcd_preserve_glitches_real <value>
              indicates that any repeat equal values for  a  real  net  spanning  different  time
              values  in the VCD/FST file are not to be compressed into a single value change but
              should remain for this case. Default for vcd_preserve_glitches  is  disabled.   The
              intended  use  is  for  when  viewing  analog  interpolated data such that removing
              duplicate values would incorrectly deform the interpolation.

       vcd_warning_filesize <value>
              produces a warning message if the VCD filesize is greater than the argument's  size
              in MB.  Set to zero to disable this.

       vector_padding <value>
              indicates  the  number  of  pixels  of extra whitespace that should be added to any
              strings for the purpose of calculating text in vectors. Permissible values are 0 to
              16 with the default being 4.

       vlist_compression <value>
              indicates  the  value to pass to zlib during vlist processing (which is used in the
              VCD recoder).  -1 disables compression, 0-9 correspond to the value  zlib  expects.
              4 is default.

       vlist_prepack <value>
              indicates that the VCD recoder should pre-compress data going into the value change
              vlists in order to reduce memory usage. This is done before potential zlib packing.
              Default is off.

       vlist_spill <value>
              indicates  that  the VCD recoder should spill all generated vlists to a tempfile on
              disk in order to reduce memory usage. Default is off.

       wave_scrolling <value>
              a nonzero value enables scrolling by dragging the marker  off  the  left  or  right
              sides of the wave window. A zero value disables it.

       zoom_base <value>
              allows setting of the zoom base with a value between 1.5 and 10.0. Default is 2.0.

       zoom_center <value>
              a nonzero value enables center zooming, a zero value disables it.

       zoom_dynamic <value>
              a   nonzero  value  enables  dynamic  full  zooming  when  using  the  partial  VCD
              (incremental) loader, a zero value disables it.

       zoom_dynamic_end <value>
              a nonzero value enables dynamic  zoom  to  the  end  when  using  the  partial  VCD
              (incremental) loader, a zero value disables it.

       zoom_pow10_snap <value>
              corresponds  to  the  Zoom  Pow10  Snap  menu  option. Default for this is disabled
              (zero).
