Q1: Given the following Combinational circuit, Use Verilog HDL on Quartus tool to 13 4 to 1 MUX S₁ So 2 to 1 MUX Output 1337 14 Is 4 to 1 16 MUX S₁ So 1. Write a Verilog HDL code to describe the module mux4×1 // this module name must be your last name 2. Write a Verilog HDL code to describe the module mux2×1// this module name must be your first name 3. Write a Verilog HDL code to describe the whole system structurally from its subsystems // this module name must be your university number Q2: Problem: Design and Simulation of 8-bit ALU Design an 8-bit ALU circuit that receives two 8-bit input numbers X [7:0] and Y [7:0], and produces a 8-bit output z[7:01, an output carry Cout, an overflow flag Ov, and Zero flag. The circuit implements the following 12 functions based on a 3-bit control input C [3:0]: Function Addition: Z-X+Y Subtraction: Z-X-Y Reminder: Z=X&Y Bitwise AND: Z=X&Y Code 000 001 010 011 100 101 Bitwise OR: Z-XIY Concatenate: Z-(X[3:0] Y[3:0]) 110 Equality: Zero-XY 111 Less than: Cout-X<Y Notes: a) Show the block diagram design of your 8-bit ALU using components like Adder, Multiplexor, etc. as needed. b) Model each component separately. You should have different modules for the adder, multiplexer, etc. c) Write a Verilog test scenarios to test both the 8-bit ALU. Verify the correctness by simulation. d) Show snapshots of all simulation waveforms. e) Submit a report (Word or PDF document) should contain Problem description, the block diagram, a copy of the Verilog modules and the waveforms taken directly as snapshots from the simulator. In addition to building the Quartus project, you need to write down one report for each student that includes the following items:
