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.
