NAME

       tkgate - Tcl/Tk based digital circuit editor and simulator

SYNOPSIS

       tkgate [-xqs] [-X script] [-l file] [-p file] [-P printer] [files...]

DESCRIPTION

       TkGate  is  a  graphical  editor  and  event  driven simulator for digital circuits with a
       tcl/tk-based interface. Supported circuit elements include basic gates  (AND,  OR,  etc.),
       tri-state   gates,   adders,   multipliers,   registers,  memories  and  mos  transistors.
       Hierarchical design is also supported with support for user defined  modules.  Save  files
       are based on the Verilog netlist format.

OPTIONS

       The options are as follows:

       -X script      Automatically  start  the  simulator  and  execute the specified simulation
                      script.

       -p file        Print circuit to file without starting GUI.

       -P printer     Print circuit to printer without starting GUI.

       -l file        Read the specified file as a library.

       -x             Automatically start the simulator.

       -q             Suppress startup messages.

       -s             Excute with a synchronous X server connection. This option is primarily for
                      debugging.

       -L lang        Specify  a  locality  to  use  if  tkgate  has  been configued for Japanese
                      support. The locality should be either "ASCII" for English, or  "ja_JP.EUC"
                      for  Japanese.  This  option  can  also  be  set  via  the LANG environment
                      variable.

HISTORY & CREDITS

       TkGate begin life as an undergraduate project at Carnegie Mellon University (CMU) in 1987.
       At  that  time  it  was  called  simply  'gate'  and  ran under the 'wm' window manager, a
       windowing system developed at CMU before X11 was widely used. In this incarnation  it  was
       used  by  students  in  the  computer  architecture  course  at  CMU  to  develop a simple
       microprocessor (dubbed "The Bat Computer"). After laying dormant for several years, it was
       resurrected  in 1991 and ported to run under X11 with the Xlib API. In this incarnation it
       was used several times by students in the introductory digital logic course, but after the
       author graduated and left CMU, it went into hibernation again. This Tcl/Tk incarnation was
       begun in 1998. While there is certainly some cruftyness in the  implementation  in  places
       due  to  the multiple reincarnations, many new features have been added since the older wm
       and X11 versions, and the interface has been made much easier to use.
