4.5.1. Increased Design Complexity

Try these first

1. 1.

   What does increased design complexity mean in the context of BIST?

   Hint

   Think about how incorporates more elements into the circuit.

2. 2.

   Explain stuck-at faults.

   Hint

   Consider how a light switch might get stuck in the 'on' position.

3. 3.

   What is a significant downside of integrating BIST into circuit design?

   • Increased Fault Detection
   • Increased Design Complexity
   • Reduced Power Consumption

   Hint

   Think about the balance between self-testing capabilities and design simplicity.

4. 4.

   True or False: BIST is always effective for detecting all fault types.

   • True
   • False

   Hint

   Consider the limitations of BIST as discussed in class.

5. 5.

   Design a circuit that integrates BIST for a simple flip flop. Discuss the potential complexities and how you will ensure high fault coverage.

   Hint

   Consider what fault types you might face in a flip flop and how you can accommodate them in your design.

6. 6.

   Evaluate a hypothetical mixed-signal BIST setup for a sensor. Analyze its effectiveness and suggest improvements.

   Hint

   Reflect on mixed signal characteristics and how they differ from digital-only systems.
