2-bit adder lab report

[Oddz313]

I'm doing a lab report from the quartus 2 software I used and compiled and simulated. waveform and timing from schematic of 2 full adders connected. What is the boolean equation of a 2 bit adder. thank you

Sum = input 1 xor input 2 xor Carry_in
Carry = (input 1 and input 2) or (input 2 and Carry_in) or (Carry_in and input 1)

Google it for operation of Full Adder
