tkgate - 2.1+repack-3 main

TkGate is a digital circuit editor and simulator with a Tcl/Tk based
interface. TkGate includes a large number of built-in devices including basic
gates, memories, ttys and modules for hierarchical design. The simulator can
be controlled either interactively or through a simulation script. Memory
contents can be loaded from files, and a microcode/macrocode compiler (gmac)
is included to create tkgate memory files from a high-level description. The
simulator supports continuous simulation, single step simulation (by clock or
epoch) and breakpoints. Save files are in a Verilog-like format.
.
TkGate also includes a number of tutorial and example circuits which can be
loaded through the "Help" menu. The examples range from a simple gate-level
3-bit adder to a 16-bit CPU programmed to play the "Animals" game.
.
TkGate has a multi-language interface with support for English, Japanese,
French and Spanish.
