The test bench would be a structured test bench including:
1. Parameter definitions
2. DUT Input regs
3. DUT Output wires
4. DUT Instantiation
5. Initial Conditions
6. Test Vectors
7. Debug output
Our documentation will provide you a clear list of all register declarations, variables and other constructs used in the coding.
To give a further proposal, we would need more information on the nature of DUT that you need to be tested.
