Hi,

Here are some links to Mailey and Moore to finite state machines :

or software example :

Re: Statemachine

State machine in verilog
---------------------------------------------------
always @(posedge CLK)
begin
STATE0 = next_STATE0;
STATE1 = next_STATE1;
STATE2 = next_STATE2;
STATE3 = next_STATE3;
STATE4 = next_STATE4;
end

always @ (RESET or STATE0 or STATE1 or STATE2 or STATE3 or STATE4)
begin

if ( STATE4 | RESET ) next_STATE0=1;
else next_STATE0=0;

if ( ~RESET & STATE0 ) next_STATE1=1;
else next_STATE1=0;

if ( ~RESET & STATE1 ) next_STATE2=1;
else next_STATE2=0;

if ( ~RESET & STATE2 ) next_STATE3=1;
else next_STATE3=0;

if ( ~RESET & STATE3 ) next_STATE4=1;
else next_STATE4=0;
end
