Try these first

1. 1.

   What does SoC stand for?

   Hint

   Think about the integration of components.

2. 2.

   Name one benefit of using the Core Test Access Mechanism.

   Hint

   Consider testing efficiency.

3. 3.

   What does IEEE 1500 establish for core testing in SoC?

   • Standardized interface
   • Random access
   • Physical probing

   Hint

   Think about the primary purpose of the standard.

4. 4.

   True or False: The Core Test Access Mechanism allows independent testing of each core in an SoC.

   • True
   • False

   Hint

   Reflect on the definition of the mechanism.
