4.3.1. Logic Built-in Self-Test (Logic BIST)

Try these first

1. 1.

   What does Logic BIST stand for?

   Hint

   Look at the title of the section!

2. 2.

   Name a type of fault that Logic BIST can detect.

   Hint

   Think about faults in digital logic.

3. 3.

   What is the main focus of Logic BIST?

   • Testing audio circuits
   • Testing digital logic circuits
   • Testing mechanical systems

   Hint

   Think about the context of Logic BIST.

4. 4.

   True or False: Logic BIST only detects errors in analog circuits.

   • True
   • False

   Hint

   Remember the type of circuits Logic BIST is meant for.

5. 5.

   Design a simple Logic BIST framework for a 2-input AND gate. Describe how you would generate test patterns and analyze response.

   Hint

   Think about the functioning of a 2-input AND gate and how you could stimulate it.

6. 6.

   Critically analyze the advantages and disadvantages of incorporating Logic BIST into a chip design intended for high-reliability applications.

   Hint

   Consider both sides of using self-testing techniques in critical environments.
