7.1. Introduction to Fault Modeling and Simulation

Try these first

1. 1.

   What is fault modeling?

   Hint

   Think about what we want to prevent before manufacturing.

2. 2.

   Name a type of fault simulation.

   Hint

   Think about how we check for faults in circuits.

3. 3.

   What is the primary purpose of fault modeling?

   • To improve performance
   • To predict faults
   • To reduce costs

   Hint

   Think about prevention rather than reaction.

4. 4.

   Fault coverage analysis measures the effectiveness of test vectors in detecting faults. True or False?

   • True
   • False

   Hint

   What do you think happens when we have comprehensive tests?

5. 5.

   Analyze a circuit design that has multiple fault points and propose a fault modeling approach.

   Hint

   Break the design down into its components and assess each part.

6. 6.

   If the fault coverage is only 75%, what steps would you take to improve it?

   Hint

   What are common types of faults that may not have been tested?
