Write a Verilog code that implements a 2 8-bit input calculator that performs the follwoing operations: addition, subtraction, multiplication, and exponentiation 2^y

1) The addition and subtraction operations should be built on carry look ahead adder

2) The multiplication operation should be built on booth encoding multiplier

Please provide codes for BOTH the calculator design module AND the Testbench module.

Thumbs up will ONLY be given if the codes work and the criteria of carry lookahead adder and booth encoding multiplier is met!
