3.2.1. Types of Fault Models

Try these first

1. 1.

   What is a stuck-at fault?

   Hint

   Think about signals that don't change.

2. 2.

   Give an example of a bridging fault.

   Hint

   Consider what happens when two wires touch.

3. 3.

   What is a stuck-at fault?

   • A fault that causes signals to be incorrect
   • A signal stuck in one state
   • A connection error

   Hint

   Consider what happens when signals don't change.

4. 4.

   True or False: Bridging faults can lead to unexpected logic outputs.

   • True
   • False

   Hint

   Think about how connections affect signals.

5. 5.

   Consider a digital circuit showing erratic behavior. Propose a methodology to detect both bridging and transition faults efficiently.

   Hint

   Think about multi-faceted testing approaches.

6. 6.

   How would you approach a situation where you suspect delay faults are sabotaging circuit performance at high speeds?

   Hint

   Consider tools for measuring signal integrity.
