A very easy-to-use but complex Gate-Simulation. You can simulate various gatters like AND, NAND, OR, NOR, NOT, XOR. And also build Flip-Flops, Full Adders and other compley structures. In other words its a register-Transfer Simulation of Hardware-Processes.

Features:

• Gate Simulation
• FlipFlops
• works on nearly all Operating systems
• Register-Transfer-Simulation
• neat GUI
• free and Open-Source
• very performant
• full-functional Applet-Version
• a Only-Display-Applet-Version (no need of signing the Applet)
• BUS-System
• OpenGL and Canvas Rendering
• Compatible with the Cir-Fileformat (http://gkinf.de)
• Load and Save the Grid
• Dragging and Zooming
• Over 50 different Elements
