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.

There are also 2 Applet-Versions - the full Version and a only-Display-Version

Try out the examples ("Components"-Tab -> Choose a Circuit -> Add Button)

Leave the Edit-Mode to control interactive elements
