8.2.2. Built-In Self-Test (BIST)

Try these first

1. 1.

   What does BIST stand for?

   Hint

   Think about what the system can do by itself.

2. 2.

   Name one component of BIST.

   Hint

   Which components help the system generate its own tests?

3. 3.

   What does BIST enable a system to do?

   • Test itself
   • Require external tools
   • None of the above

   Hint

   Think about BIST's primary function.

4. 4.

   True or False: BIST can function effectively without any additional circuitry.

   • True
   • False

   Hint

   Consider what is needed for BIST to operate.

5. 5.

   Design a simple BIST implementation plan for a new consumer electronic device, considering advantages and potential challenges.

   Hint

   Think about the right balance of features versus constraints.

6. 6.

   Evaluate a case where a BIST system failed to identify a fault during operations. What steps could be taken to enhance its detection capabilities?

   Hint

   Consider what types of faults might not have been addressed in the original plan.
