Question $1.$

Task $1$

Draw a schematic for a $32-$bit ALU that has the following operations:

$\backslash$table$[[$ALUControl$,$Function$],[000,$AND$],[001,$OR$],[010,$XOR$],[011,$ADD$],[100,$SUBTRACT$]]$

Table $1$: Required ALU functions

Task $2$

Using the IIDL of your preference, implement the ALU you designed above $($behavioral or structural modules are acceptable$).$

Task $3$

Write a test bench for the ALU implemented in the IIDL above. Write test vectors that test nominal functionality as well as corner casses. Explain a test case for each of the functions in Thask $1.$ Use it to test your ALU.
