nandbench — live digital logic circuit simulator
nandbench is a free, web-based, real-time digital logic circuit simulator and editor that runs entirely in your browser — no install, no account. Drag in logic gates, wire them up, flip inputs, and a fast event-driven engine evaluates the circuit live while catching the mistakes students burn hours on. Sayısal mantık devre simülatörü — tarayıcıda çalışır, kurulum gerektirmez.
What you can do
- Build combinational and sequential circuits from AND, OR, NOT, NAND, NOR, XOR and more.
- See live error detection as you wire: bit-width mismatches, multi-driver conflicts, oscillation and floating inputs.
- Step through 47 guided lessons from bits to a small datapath.
- Look up any term in a 90-term interactive glossary.
- Group circuits into reusable hierarchical sub-circuits.
- Export your design to Verilog.
Learn digital logic, step by step
The built-in curriculum follows a one-semester digital logic design course:
- Foundations — bits, number systems, boolean algebra.
- Gates — logic gates and minimization.
- Combinational — adders, multiplexers, decoders, comparators, ALU primitives.
- Sequential — latches, flip-flops and timing.
- Registers — registers, counters, shift registers.
- Memory — RAM, ROM, addressable storage.
- Finite state machines — Moore and Mealy FSMs.
- Datapath — ALU, register file, a tiny CPU.
- Beyond — hazards, pipelining hints, tooling.
A modern Logisim / CircuitVerse alternative
nandbench renders on a fast canvas and simulates with an event-driven, four-valued (0 / 1 / X / Z) engine, so it stays smooth on large circuits where cycle-based simulators slow down. It is built for learning digital logic design, computer organization and logic circuits courses.
