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.

       TkGate documentation can be found at:

OPTIONS

       The options are as follows:

       -X script      Automaticaly 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	      Automaticaly 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 Eng-
		      lish, 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 stu-
       dents 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 rein-
       carnations, many new features have been added since the older wm and X11 versions, and the interface has been made much easier to use.
