i need a Verilog code that correspond with the design i made $?$

I should get the infomation from my switch one $(0$:$7)$ and the other $(8$:$16)$ and the FSM is to select the operation which are $3$ bit number that the ALU going to preform using button like how i have it the middle change mode while the four select the opration. i should use all four segment as well so it should display in two place led and $4$ segment.

Your design should allow the user to select the following operations: addition, subtraction, multiplication, division $($need to handle $$divide$-$by$-$zero$),$ logical shift $($either left or right$),$ bitwise

AND, and bitwise OR$.$ It should only allow at most one operation to be conducted at a time. You

may assume inputs are unsigned numbers. Display the output on the seven segment display in

decimal or hexadecimal as well as on the LED lights in binary. You should consider reusing Verilog

modules you designed in this course, such as the seven$-$segment display, etc. Note, you may use

behavioral Verilog to implement the operations instead of a structural implementation. This means

you can use the $+,,,/,$ & $,|$ operators rather than having a module that does the operation

from the ground up$.$ You may choose to use all $16$ DIP switches on your Basys board for inputs,

and use buttons to encode the operations. Or use $8$ DIP switches in combination with buttons to

load different registers then use $3$ DIP switches to encode the operation.
