1.5.3. Functional DFT Methods

Try these first

1. 1.

   Define Functional Design for Testability.

   Hint

   Consider the purpose of these methods.

2. 2.

   What is a test bench?

   Hint

   Think about where we test components.

3. 3.

   What is the purpose of Functional DFT methods?

   • To modify circuit layout
   • To test operational behavior of systems
   • To increase manufacturing speed

   Hint

   Consider what happens post-design.

4. 4.

   True or False: A test bench is used for simulating hardware testing.

   • True
   • False

   Hint

   Think about the stages of design.

5. 5.

   Design a test bench for a simple circuit that includes a flip-flop. Explain the scenarios you would test and why.

   Hint

   What states need to be validated?

6. 6.

   Using fault injection, outline a test plan to validate a digital control system under faulty sensor conditions.

   Hint

   Consider how sensor inaccuracies can impact the system.
