5.4.4. Improved Yield and Reliability

Try these first

1. 1.

   Define yield in the context of manufacturing.

   Hint

   Think about the output of a manufacturing process compared to what was intended.

2. 2.

   What is reliability in digital circuits?

   Hint

   Consider a circuit's ability to function correctly continuously.

3. 3.

   What does a higher yield indicate in manufacturing?

   • More defects
   • Fewer functional products
   • Higher functional yield

   Hint

   Think about the success rate in manufacturing.

4. 4.

   True or False: Reliability refers to the number of times a product can be tested without failure.

   • True
   • False

   Hint

   Consider what reliability means in real-world applications.

5. 5.

   In a production line of 1000 circuits, if 850 are functional, what is the yield? How does implementing scan chains change this?

   Hint

   Review how yield is calculated.

6. 6.

   Imagine a scenario in a production factory where a design change has decreased reliability. How might scan chains assist in restoring reliability?

   Hint

   Focus on how increased testing can uncover design flaws.
