6.5. Best Practices for Implementing Scan Chains

Try these first

1. 1.

   What is the benefit of early integration of scan chains?

   Hint

   Think about the stage in the design process.

2. 2.

   Define hierarchical design in your own words.

   Hint

   Consider how this affects testing.

3. 3.

   What is the primary benefit of early integration of scan chains?

   • Increased complexity
   • Reduced troubleshooting time
   • Higher power consumption

   Hint

   Think about the overall design process.

4. 4.

   True or False: Hierarchical design can enhance test coverage.

   • True
   • False

   Hint

   Consider its effect on manageability.

5. 5.

   Create a scenario where not using hierarchical design in a large digital system could result in failure. Outline how it could have been avoided.

   Hint

   Think about the advantages of reduced complexity in testing.

6. 6.

   Evaluate the implications of skipping the simulation phase in the implementation of scan chains in a new product.

   Hint

   Consider why verification is critical before final production.
