ALU

This project implements a 4-bit Arithmetic Logic Unit (ALU) that performs logical and arithmetic operations on two 4-bit binary inputs, A and B, controlled by a 2-bit select signal S. Depending on the value of S, the ALU outputs a bitwise XOR (S = 00), bitwise AND (S = 01), bitwise OR (S = 10), or a 4-bit binary addition (S = 11). The design was verified using multiple test cases to ensure correct logical behavior and accurate arithmetic results, demonstrating proper control decoding and functional correctness of the ALU operations.
