Hallo guys , I am first year electrical Engineer Major & we are asked to design and simulate using Multisim a small ALU , The ALU is a 4-bit digital circuit that performs addition, subtraction, ANDing, ORing, complementing, XORing, XNORing and comparison. The ALU also outputs if the answer is negative, zero, or overflow. Use 3 bits to select the function of the ALU. I am kinda clueless where should i start , any hints on Multisim or how should i start this ? it would be really really appreciated if anyone Can contribute helping me or pointing me in the right direction .
