Verilog code:

1)

a. Create and add the Verilog module, named add_two_values_task, which defines a task called add_two_values. The task will take two 4-bit parameters, add them, and output a 4-bit sum and a carry. The module will call the task with the operands received via input ports and outputs the result.

b.Create and add a Verilog module, called add_two_values_function, which defines a function called add_two_values that takes two 4-bit parameters, add them, and return a 5-bit sum. The module will have two 4-bit input ports and one 5-bit output port. It will call the function.
