7.5.1. Limited Coverage for Complex Faults

Try these first

1. 1.

   What does fault coverage mean?

   Hint

   Think about it in terms of a test catching all possible issues.

2. 2.

   Why is accuracy in fault models important?

   Hint

   Remember how we discussed the impact on system reliability?

3. 3.

   What is the main limitation of fault modeling and simulation?

   • They are always accurate
   • They may not detect every complex fault
   • They are too simple

   Hint

   Think about how systems can fail in unexpected ways.

4. 4.

   True or False: Fault simulation tools have no limitations at all.

   • True
   • False

   Hint

   Reflect on what we’ve discussed regarding faults.

5. 5.

   Design a fault detection strategy for a complex system, considering at least three different types of faults.

   Hint

   Consider how combining different methods improves coverage and reduces risk.

6. 6.

   Analyze the trade-offs between computational cost and fault coverage in simulations, proposing solutions for balancing them.

   Hint

   Think about prioritizing significant areas of the circuit for testing.
