Finite State Machines (FSMs) are at the heart of most digital design. The basic idea of an FSM is to store a sequence of different unique states and transition between them depending on the values of the inputs

所以定义8种状态parameter idle=0,start=1,data0=2,data1=3,data2=4,data3=5,data4=6,data5=7,data6=8,data7=9,wait_stop=10,stop=11;reg[3:0]state,next_state;always@(*)begincase(state)idle:next_state=(in==1)?
When coding state machines in Verilog or SystemVerilog, there are a few general guidelines that can apply to any state machine: If coding in Verilog, use parameters to define state encodings instead of‘definemacro definition. Verilog‘definemacros have global scope; a macro defined in one module...
State Machines Abstract There are two types of state machines: Mealy machines and Moore machines. You can model both types of machines in Verilog. The difference between Mealy and Moore machines is in how outputs are generated. In a Moore machine, the outputs are a function of the current ...

Finite State Machines in VHDL and Verilog 22.6Summary Finite State Machinesare a fundamental technique for designing control algorithms in digital hardware. This chapter of this book is purely an introduction to the key concepts and if the reader is not already fully familiar with the basic concepts...
