1Functional Specifications

Design a Verilog program that performs the basic arithmetic and logic operations (ALU) on two

3-bit binary inputs, and displays the outcome on 7-segments.

• Arithmetic operations: addition and subtraction

• Logic operations: AND and OR

• Displaying results:

– For addition and subtraction: display the result using decimal digits

– For logic AND and OR: display the result using binary digits

2 Objectives

Demonstrate the ability to

1. program in Verilog to describe digital logic circuit on behavioral and gate level;

2. use Xilinx ISE for coding and synthesizing the logic design;

3. use Spartan 3 development board to implement and verify the design.
