7. Fault Modeling and Simulation

Try these first

1. 1.

   Define Fault Modeling.

   Hint

   Think about the purpose of this process.

2. 2.

   What is a Stuck-At Fault?

   Hint

   Consider how this might limit circuit function.

3. 3.

   Which fault model assumes that a signal remains constant regardless of inputs?

   • Transition Fault
   • Stuck-At Fault
   • Delay Fault

   Hint

   Think about a signal’s behavior when it fails.

4. 4.

   True or False: Functional Simulation focuses on assessing timing accuracy.

   • True
   • False

   Hint

   Consider the definitions of both simulation types.

5. 5.

   Design a hypothetical circuit affected by various fault models and discuss how you would mitigate these faults using fault simulation.

   Hint

   Think about the steps you would take to ensure all potential faults are covered in your design.

6. 6.

   Analyze a complex PCB design for fault coverage and create a report on its susceptibility to bridging faults.

   Hint

   Envision yourself detecting real-world faults and identifying measures for prevention.
