Design a combinational logic circuit using VHDL coding that executes the arithmetic and logic

unit $($ALU$)$ functions below for the given inputs for registers $A,B$ and $G,$ which are $8$ bits each. $x$

is a binary input. Then execute the following mathematical operation:

TABLE $8-2$

Function Table for ALU

$($a$)$ Show and explain your VHDL code $(25$ points$).$

$($b$)$ Show that your VHDL code is synthesized successfully $(25$ points$).$

$($c$)$ Show and describe the RTL schematics $($register transfer level circuit$)$ of your ALU $(25$ points$).$

$($d$)$ Prepare a simulation code that tests each functionality. Explain the functionality using the

behavioral model $(25$ points$).$
