## What is Digital Simulator bitGateLab?

bitGateLab Digital is a digital electronics lab on your PC, phone or tablet: design a circuit with logic gates, watch it run live, get its truth table and Karnaugh map, check the timing diagram and build it on a 3D breadboard with step-by-step wiring. Everything works offline, with no account.

DESIGN AND SIMULATE
• AND, OR, NOT, NAND, NOR, XOR, XNOR and buffer gates; inputs, switches, push buttons, DIP banks, LEDs, LED strips and bar graphs, 7- and 16-segment displays, buzzer.
• Sequential logic: D, T, JK and SR flip-flops, clock, crystal, counters, 555 timer, word generator, serial monitor.
• Components: multiplexers, buses, ROM and RAM, H-bridge, motor, optocoupler, registers.
• Group any part of the circuit into a reusable block with its own pins.
• Undo and redo, copy and paste, named and colored wires, grid and automatic fit.

TRUTH TABLE AND KARNAUGH
• Type a boolean equation or fill in the truth table and turn it into a circuit with one tap.
• Karnaugh maps from 2 to 8 variables, with groupings, canonical form, minterms or maxterms.
• Step-by-step simplification naming each law applied, NAND form and Verilog export.
• From the circuit back to the truth table or the Karnaugh map.

TIMING DIAGRAM
• Every input combination as a binary counter, with the hex value of each cycle.
• A and B probes to measure intervals, X and Z levels, slopes and propagation delay per logic family (TTL, CMOS...).
• Export to PDF.

3D BREADBOARD
• Your circuit becomes a real build on its own: 74-series chips, resistors, LEDs, switches and wires on one or more breadboards.
• Step-by-step guide hole by hole (for example 44i → 12i), bill of materials and net list.
• Move chips, LEDs and switches where you like, recolor wires, isolate a net or a single wire, undo and redo.
• Labels on every input and LED, free rotation, zoom and image capture.

MICROCONTROLLERS AND PROGRAMMABLE LOGIC
• MCU51 (8051-compatible) and MCU14 (14-bit): program in C or assembly, assemble and single-step with registers, ports, timers, interrupts and UART.
• 16V8, 20V8 and 22V10 PLDs: equations, fuse map and JEDEC file.
• Ready-made examples: counters, blinkers, traffic lights, serial communication and more.

SHARE AND SAVE
• Save your circuits with version history; share them as a file, a link or a QR code.
• Export images as SVG, PNG, JPEG, WebP or PDF, and code as Verilog.
• Number systems calculator, two's complement and binary operations with flags.

FOR LEARNING AND TEACHING
• Reference of boolean algebra laws and theorems.
• State table and state diagram of your sequential circuits.
• Large-button interface, comfortable on PCs, phones and tablets; light and dark themes.
• 16 languages: Spanish, English, Portuguese (Brazil and Portugal), French, German, Italian, Russian, Polish, Dutch, Turkish, Chinese, Japanese, Korean, Arabic and Hindi.

PRIVACY
No account, no cloud and no ads: your circuits are stored only on your device. Something not working? Settings → Report a problem sends your message with the app version, device model and a technical log, with no personal data.
