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 and the current state of the machine. The FSM can be of two types Moore ...
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 ...
