i want testbench

Task 1 (20 points) By using Verilog language construct 12-bit Arithmetic and Logic Unit (ALU) which will be able to execute the following instructions: Rotate left, Multiplication, Greater comparison, Logical XOR, Logical XNOR, Subtraction, Rotate right, Logical NAND, Division, Logical OR, Equal comparison, Addition, Logical NOR, Logical shift left, Logical shift right. Task 2 (20 points) Construct testbench for circuit from task 1 by using Verilog language and then create appropriate circuit. P.S. For each task it is necessary to provide links to projects implemented on the site http://circuitverse.org/simulator otherwise you will get 0 points for the corresponding task
