5.5.3. Limited Fault Coverage in Complex Systems

Try these first

1. 1.

   What is fault coverage?

   Hint

   Think about the purpose of a test.

2. 2.

   Name one effect that can limit fault coverage.

   Hint

   Consider unintended interactions between circuit elements.

3. 3.

   What term describes the ability to identify faults in a digital circuit?

   • Reliability
   • Fault Coverage
   • Speed

   Hint

   Think about the goal of testing.

4. 4.

   True or False: Parasitic effects can help in detecting faults in a circuit.

   • True
   • False

   Hint

   Consider the influence of unforeseen effects.

5. 5.

   Analyze how the introduction of parasitic effects in high-frequency circuits could lead to undetected faults and suggest a mitigation strategy.

   Hint

   Consider types of equipment that can measure such effects.

6. 6.

   In a multicore system, how do resource-sharing issues potentially create faults that are challenging to detect?

   Hint

   Think about how interactions can be oversighted.
