Write a behavioral verilog module 2mux2in4b and a test bench 2mux2in4b_tb for a 2-input, 4-bit MUX with data input vectors D0 and D1, and an output vector Y and index them from 1 to 4. For each value of the function inputs, the test bench shouldd check that the output is correct for all combinations of data-input calues and display an error message if it is incorrect.
| Inputs | Outputs | ||||
| G | S | 1Y | 2Y | 3Y | 4Y |
| 1 | x | 0 | 0 | 0 | 0 |
| 0 | 0 | 1D0 | 2D0 | 3D0 | 4D0 |
| 0 | 1 | 1D1 | 2D1 | 3D1 | 4D1 |
