VHDL design of finite state machines

The design method of FSM based on VHDL is introduced, which doesn’t need state implication, state distribution, state coding, output and impulse function, and doesn’t need diagram drawing. All tasks can be carried out by EDA. The feature and the advantage of this design method are proved with an example of wave generator design and the validity of this design is testified by simulation. The modern digital system design of FSM is realized based on VHDL.
