Fibonacci Code

Modfied for only 8 outputs. You need to make your pin assignments in Quartus as LED[0],LED[1],LED[2],LED[3]... etc.

module fib( 
    input               clk,
    input               reset_n,
    output         LED,
);
reg  prev;
reg  actual;
assign  LED = actual;
always @(posedge clk or negedge reset_n) begin
    if(!reset_n)    begin
                                prev    <= 8'd0;
                                actual  <= 8'd1;
    end else begin
                                prev    <= actual;
                                actual  <= actual + prev;
    end
