A Finite State Machine (FSM), or Finite Automata, is a mathematical model of a system whose state is capable of changing. These systems have characteristics or behaviors that vary depending on the current state. In general, FSMs are divided into two types: FSM...

Basically, FSM serves to describe the workings of a sequential circuit. Therefore, the VHDL code of an FSM is not much different from the VHDL code of an ordinary sequential circuit, which uses a process statement (behavioral model). There are many methods tha...

Moore Machine This FSM has two states: ST0 and ST1. In the ST0 state, the FSM outputs '0', and in ST1, the output is '1'. This FSM also accepts two inputs: CLR and TOG_EN. The CLR input returns the FSM to ST0, while TOG_EN determines whether the FSM can switch...
