There are a lot of the software and online tools available for simulating the circuit or embedded systems, among them Proteus holds the significant position which is equally popular among students and professionals.
So by simulation of the circuit or embedded system you can pin point the glitches of the coding and also the abnormal behavior of the circuit. Simulation is the imitation of the circuit behavior just as it behaves when it is implemented physically in real life. Before you build the prototype of the circuit it is always beneficial that you simulate it.
