7.2.1. Types of Fault Models

Try these first

1. 1.

   Explain what a Stuck-At Fault Model (SAF) is.

   Hint

   Think about fixed states of signals.

2. 2.

   What does the Transition Fault Model (TF) address?

   Hint

   Consider changes in signal behavior.

3. 3.

   What does the Stuck-At Fault Model assume?

   • Signals can traverse freely
   • Signals are stuck at a set state
   • Signals are moving in and out

   Hint

   Think of a scenario where a signal can't change.

4. 4.

   Transition Faults are primarily concerned with:

   • True
   • False

   Hint

   Recall how timing impacts signal changes.

5. 5.

   You are designing a digital circuit that requires robust testing. The circuit needs to operate at high speeds. Which fault types should you prioritize and why?

   Hint

   Consider the operational speed and how signals are affected by time.

6. 6.

   Describe the testing strategy for ensuring there are no bridging faults in a circuit you develop.

   Hint

   Think of tools and methods that help locate wiring cases.
