4- Write VHDL descriptions for component that implement the following functions. Note that each component will have inputs A, B, C, and D, and a single output, F1 (or F2, F3). F1(A,B,C,D) = '1' if and only if all inputs (A, B, C, and D) are '1' or all inputs are '0'. F2(A,B,C,D)='1' if and only if two of the inputs = '1'. F3(A,B,C,D)='1' if and only if the number of inputs that = '1' is odd.

The input and output ports are all single bit. Simulate the model using Xilinx ISE Software to demonstrate correct operation. For this assignment, you should turn in the filled-in Karnaugh maps for the problems above, printouts of your VHDL source code, and printouts of your VHDL simulations showing correct operation for all the required input combinations.
