Hi,

I think the best way is you try to write it first.
If you face any difficulties, then let us know.

We can help you from there onwards.

1. U can generate the test vecor from C(ramdom) or some else verification software.
2. use $readmemh.
3. comparing vector from input files with data output from adder.

Go through the Douglus Perry. In that book number of ways are given for writting the test bench.

Writing the testbench for fulladder and Mux are as simple as writing their design.

Try first and even then you don't get, ask
