Question: Prob 3: Compare 4-bit full adder and 4-bit carry look-ahead adder a) Assuming that each gate, no matter which type, will have 1 time unit

Prob 3: Compare 4-bit full adder and 4-bit carry look-ahead adder

a) Assuming that each gate, no matter which type, will have 1 time unit delay. From the logic design diagram, estimate the worst case totol delay of these 2 types of 4-bit adders. Find out the delay ratio between these two adders.

b) Using Vivado, simulate both designs and use 0101+1101 as the example, show the reported delays. Find out the delay ratio between these two adders.

c) Are the ratios in a) and b) the same?
