TKGATE(1) General Commands Manual TKGATE(1) 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 in- clude basic gates (AND, OR, etc.), tri-state gates, adders, multipli- ers, 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: https://bitbucket.org/starling13/tkgate OPTIONS The options are as follows: -X script Automatically start the simulator and execute the speci- fied 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 op- tion 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 vari- able. HISTORY & CREDITS TkGate begin life as an undergraduate project at Carnegie Mellon Uni- versity (CMU) in 1987. At that time it was called simply 'gate' and ran under the 'wm' window manager, a windowing system developed at CMU be- fore X11 was widely used. In this incarnation it was used by students in the computer architecture course at CMU to develop a simple micro- processor (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 im- plementation 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.
