DigitalCircuit Homework 1- Fibonacci Calculator-VHDL Solved

Description

Mathematically, we can define the n-th Fibonacci number as the sum of the (n-1)-th and (n-2)-th.

Given the following entity declaration for a Fibonacci Calculator, complete the architecture to provide a behavioral description for the Fibonacci calculator.

entity Fibonacci_Calculator is

      port (   clk           : in  std_logic; 

   data_in  : in  std_logic_vector (3 downto 0);      load_enable : in  std_logic;        data_out  : out std_logic_vector (9 downto 0)); end Fibonacci_Calculator;

architecture behavioral of Fibonacci_Calculator is

(Note: Do not use algorithmic state machine)  You have to submit two files:

1. A VHDL code to implement your Design.
2. A testbench file to simulate and test your design.
   1. You have to cover all the possible cases for the input data:
   2. For each case you have to:
      1. Select a test value for data_in
      2. Activate the load_enable signal for at least one clock cycle.

• The Fibonacci number should be calculated at the rising edge of the input clock.
