7.3.2. Functional Simulation

Try these first

1. 1.

   What is functional simulation?

   Hint

   Think about why we simulate instead of just manufacturing.

2. 2.

   What role does a testbench play?

   Hint

   Consider what you need to check correctness.

3. 3.

   What is the primary purpose of functional simulation?

   • To create a physical prototype
   • To verify circuit correctness
   • To test manufacturing processes

   Hint

   Think about what happens first in the design process.

4. 4.

   True or False: A testbench must always include fault injection.

   • True
   • False

   Hint

   Consider the purpose of a testbench.

5. 5.

   Consider a digital lock circuit. Design a testbench that simulates various input scenarios, including correct codes, incorrect codes, and unauthorized access attempts. Discuss what outputs you expect.

   Hint

   Think about all the possible user interactions with the lock.

6. 6.

   Discuss the process of implementing fault injection for a communication circuit that uses packet transmission. What types of faults could you introduce, and what would you expect to observe?

   Hint

   Consider errors that could disrupt the integrity of data transmission.
