3.2.6. Verification

Try these first

1. 1.

   What is the primary goal of the verification phase?

   Hint

   Think about what would happen if there were errors in the final product.

2. 2.

   Define what a testbench is.

   Hint

   What tool do we use for testing our designs?

3. 3.

   What is the primary purpose of verification in digital circuit design?

   • To implement the design
   • To ensure functionality matches specifications
   • To create the bitstream

   Hint

   Think about why we would want to verify something before finalizing it.

4. 4.

   True or False: A testbench is used to provide inputs and monitor outputs during verification.

   • True
   • False

   Hint

   Recall what a testbench is used for in our discussions about verification.

5. 5.

   Design a testbench for a 4-bit binary counter and outline the inputs and expected outputs for verification.

   Hint

   Consider how you would simulate the clock and the counting mechanism in your testbench.

6. 6.

   Imagine you find a logic error after implementing a design. Describe the steps you'd take to debug the issue using your testbench.

   Hint

   Break down the testbench analysis in a systematic way to isolate the faulty logic.
