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 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.
