Digital logic is the foundation of every computer, smartphone, and microcontroller on Earth. At its core, computation reduces to just a handful of Boolean operations — AND, OR, NOT — combined in clever ways to perform arithmetic, store memory, and execute programs.
These simulations let you build and observe logic circuits in real time. Toggle inputs on Boolean gates, generate truth tables, watch carry bits propagate through adders, observe flip-flops latch and hold state, and design finite automata that recognize patterns. Every transistor in a modern CPU is doing exactly what you see here — billions of times per second.
