DigicalSim (formerly: iLogicDesigner) is a full featured app which assists students in logic design, digital engineering, computer science and mathematics.
The app based on basic digital building blocks, logic gates. No knowledge of logic gates or digital circuits is required.
It offers the basic building blocks, wiring tools and a flexible plane to create live real-time digital circuits, ideal for anyone who wants to learn the basic principles of how computers work - especially students of digital engineering, learn how to create simple logic gates, latches, flip-flops, adders, shift registers and counters. it can help them perform complete lab experiments.
