Advanced Digital Systems DesignSolve the following questionsshow the design, test, and a screenshot of the results.Q$1$: A carry look ahead generator circuit helps speed the process of adding binary numbers bycalculating the carry bits before the addition process begins. Assuming a $6-$bit adder, and byusing Verilog design and testing:$1)$ Show how fast is the carry look ahead compared to the serial adder. Assume that thepropagation delay of any logic gate used $($ AND, NAND, OR$,$ NOR, NOT, XOR, XNOR$)$ is$10$ns$\mathrm{.}2)$ Test the circuit by performing $3$ tests on adding different numbers of your choiceShow me code and test bensh and monitor
