For each question, show the design, test, and a screenshot of the results. Q1: A carry look ahead generator circuit helps speed the process of adding binary numbers by calculating the carry bits before the addition process begins. Assuming a 6-bit adder, and by using Verilog design and testing: 1) Show how fast is the carry look ahead compared to the serial adder. Assume that the propagation delay of any logic gate used (AND, NAND, OR, NOR, NOT, XOR, XNOR) is 10ns. 2) Test the circuit by performing 3 tests on adding different numbers of your choice. Q2: A logic circuit is required to detect the presence of five consecutive ones for a serial data input line. Design this circuit using any type of flipflops of your choice. Test your circuit using the following input sequence. 1) 010111110111100 2) Random sequence of your choice. Q3: Using counters and other logic devices, design a traffic light that operates as follows: Red light for 9 seconds, Orange light for 3 seconds and green light for 12 seconds. Assume a clock frequency of 1 Hz. Show your work and results by testing the circuit for 60 seconds Q4: Design a one-input, one-output serial 2's complementor. The circuit accepts a string of bits from the input and generates the 2's complement at the output. The circuit can be reset asynchronously to start and end the operation. Test your circuit using the following input sequence. 1) 010111110111100 2) Random sequence of your choice.
