parameter [1:0] S0 = 2’b00, S1 = 2’b01,

S2 = 2’b10, S3 = 2’b11;

always@(posedge clk) begin

if (rst == 1’b0) begin

state <= S0;

end else

end state <= nextstate;

always@(state, rst, choice) begin

case (state) S0 : begin

out = 2’b00;

if (rst == 1’b1) nextstate <= S1; end

S1 : begin
out = 2’b01;
if (choice == 1’b1) nextstate <= S2; else nextstate <=S3;

end

S2 : begin
out = 2’b10;
if (rst == 1’b1) nextstate <= S0;
