1.3. Key Concepts of Design for Testability

Try these first

1. 1.

   What are Test Access Points (TAPs)?

   Hint

   Think about how engineers access signals.

2. 2.

   Describe Built-In Self-Test (BIST) in your own words.

   Hint

   How does it simplify the testing process?

3. 3.

   What do Test Access Points (TAPs) provide?

   • Enhanced performance
   • Easy access for testing
   • Higher cost

   Hint

   Consider what TAPs are designed to do.

4. 4.

   True or False: Built-In Self-Test (BIST) requires external testing equipment.

   • True
   • False

   Hint

   Think about the definition of BIST.

5. 5.

   Design a circuit and identify where you would incorporate Test Access Points. Justify your choices based on potential fault detection scenarios.

   Hint

   Think about the most common points of failure in electronic designs.

6. 6.

   Critique a hypothetical electronic system lacking observability and controllability features. What problems might engineers face in testing?

   Hint

   Consider how critical insights into internal processes are for troubleshooting.
