6.5. Best Practices for Simulation-Based Verification

Try these first

1. 1.

   What are testbenches used for in RTL verification?

   Hint

   Think about the inputs and outputs of the design.

2. 2.

   Name one advantage of using assertions in Verilog.

   Hint

   Recall how assertions function in the design.

3. 3.

   What is the main purpose of a testbench?

   • Apply test inputs to the design
   • Generate random inputs
   • Analyze output results

   Hint

   Consider what a testbench is fundamentally used for.

4. 4.

   True or False: Assertions only check the output of a design during simulation.

   • True
   • False

   Hint

   Reflect on what assertions verify.

5. 5.

   Design a simple testbench in Verilog for a 2-input AND gate, ensuring both directed and random input testing.

   Hint

   Think about how both types of stimuli could be implemented together.

6. 6.

   Reflect on a scenario in which relying solely on statement coverage might compromise design integrity. Create an example that illustrates this flaw.

   Hint

   Consider different logical branches and their real implications.
