Digital circuits are generally built up in layers, with each layer representing a different circuit function. Digital circuits are often referred to as "Ladder Logic" because they resemble the rungs of a ladder.

Ladder logic (also known as ladder diagram or LD) is a programming language used to program a PLC (Programmable Logic Controller).It is a graphical PLC programming language which expresses logic operations with symbolic notation. Ladder logic is made out of rungs of logic, forming what looks l...
This is an example of a sequence error and a timing error. It is a sequence error because the logic allows multiple sequence steps to be active at the same time. It is a timing error because it allows the process to be started at the wrong time. To fix this issue, we could update ...
