7.3.4. Fault Coverage Analysis

Try these first

1. 1.

   What is fault coverage?

   Hint

   Think about how many faults our tests can catch.

2. 2.

   Why is it essential to have high fault coverage?

   Hint

   What happens if a fault is detected after production?

3. 3.

   What does fault coverage measure?

   • The speed of a circuit
   • The percentage of detectable faults
   • The cost of testing

   Hint

   Think about what you measure in the testing process.

4. 4.

   True or False: High fault coverage guarantees that there are zero faults in the system.

   • True
   • False

   Hint

   Reflect on the statement's claim about fault detection.

5. 5.

   You're assigned to measure the fault coverage of a complex system with multiple test vectors. Discuss the steps you would take to ensure accurate assessment using fault simulation tools.

   Hint

   Think about the testing cycle and the importance of iterations.

6. 6.

   An engineer notices that fault coverage is significantly lower than expected. Formulate a plan to identify and rectify this issue in the test design.

   Hint

   Use the steps of problem-solving to structure your approach.
