Using Verilog coding, design a simple ALU with 8 - bit op erand, 3 - bit opcode and 8 - bit result . Provide comments throughout your code. Creating a test bench to test your design for one operand s co mbination and test you 8 functions of the ALU . In your report, prov ide Verilog code for each module, test bench, and timing diagram or $monitor outputs illustrating correct functionality.
