I'm working on a programming multi-part question and need an explanation and answer to help me learn.
1. In this question you are to implement the following truth table (where – represents a don’t care value) using the requested commands/styles in Verilog. Simulate each case using your testbench and then synthesize each version and submit the screen capture of the RTL view.
a b c y 0 0 0 1 0 0 1 1 0 1 0 – 0 1 1 – 1 0 0 0 1 0 1 0 1 1 0 1 1 1 1 0
Figure 1. Truth table for Question 1
a) Using concurrent continuous assignment(s)
b) Using behavioral code with case statement
c) Using behavioral code with if statement
d) Using structural code (implement the SUM-OF-PRODUCT representation of the circuit using primitive gates of AND, OR, and NOT.
e) Using reduction operators
2. In this question, you are asked to design a synthesizable ALU using the requested commands/styles in Verilog. This ALU gets two 8-bit inputs (A, B) and a 4-bit select input (S) based on which decides about the operation that should be executed (output Q is 8-bit). What follows shows these operations
: If S=0 => Addition (i.e., A+B)
If S=1 => Subtraction (A-B)
If S=2 => Multiplication (only the least 8 significant bits are shown in output) 2
If S=3 => Shift A to the left B times (and add 0 from right side)
If S=4 => Rotate A to the right B times
If S=5 => A is ANDed with B
If S=6 => A is ORded with B
If S=7 => A is XORed with B
If S=8 => A is NANDed with B
If S=9 => Complement of A is computed
Design this ALU using the following code styles:
a) Using concurrent continuous assignment(s)
b) Using behavioral code with case statement
c) Using behavioral code with if statement
3. Reconsider question 2 with the assumption that the output is a registered output, i.e., Q is loaded by the rising edge of the clock signal when reset is not active (RESET=0). For this case consider a synchronous resetting mechanism (RESET only acts in the rising edge of the CLK signal). Implement the circuit with the following styles:
a) Using behavioral code with case statement
b) Using behavioral code with if statement
4. Leveraging the concatenation operator, create a module that accepts a 64-bit input X, and swaps pairs of even-and odd bytes to produce a 64-bit output U. The output should be registered using a clock signal CLK.
5. a) Design a 4-bit counter with inputs/outputs shown in Fig. 2. It should be a synchronous counter with asynchronous resetting mechanism and work as follows:
● If ENABLE=’0’, the output keeps its previous value regardless of other input values.
● If ENABLE=’1’ and LOAD=’1’, the 4-bit input value (V) is loaded into the counter with the rising edge of the CLK signal regardless of other input values.
● If ENABLE=’1’ and LOAD=’0’, then it counts synchronously up or down with rising edge of CLK based on the value of UP (if this value is ‘1’ it counts up, otherwise it counts down).
● The RCO output becomes ‘1’ only in the following cases:
⮚ when ENABLE=’1’ and UP=’1’ and Q=’1111’
⮚ when ENABLE=’1’ and UP=’0’ and Q=’0000’ 3
Note that all cases above occurs only if CLEAR=’0”. However, if CLEAR=’1’, both Q and RCO will be reset immediately (asynchronous resetting mechanism)

b) Write a testbench for your circuit that does the following: -First it loads the value of 10 (decimal) in the counter, then starts counting down for 6 clock cycles. After that it counts up for 20 clock cycles.
c) Implement an 8-bit counter with the same specification using 2 samples of the circuit designed in part a. In this circuit RCO signal becomes ‘1’ in following cases
⮚ when ENABLE=’1’ and UP=’1’ and Q=’11111111’
⮚ when ENABLE=’1’ and UP=’0’ and Q=’00000000’
d) Write a testbench for your 8-bit counter that does the following: -First it loads the value of 122 (decimal) in the counter, then starts counting down for 124 clock cycles.
