10.3.3.1. Low-Power Test Patterns

Try these first

1. 1.

   What is a low-power test pattern?

   Hint

   Focus on how it relates to energy efficiency.

2. 2.

   Define power gating.

   Hint

   Think about how it helps save energy.

3. 3.

   What is the primary goal of low-power test patterns?

   • To increase power consumption
   • To minimize power consumption
   • To test only at high speeds

   Hint

   Think about the impact of testing on battery life.

4. 4.

   True or False: Power gating helps in extending battery life.

   • True
   • False

   Hint

   Consider how energy savings lead to longer device usage.

5. 5.

   Design a low-power test pattern for a circuit that has specific known faults. Describe your pattern and how it saves power.

   Hint

   Consider the types of faults and how frequent transitions can expose them.

6. 6.

   Evaluate the effectiveness of power gating in a real-time system that requires continuous operation.

   Hint

   Think about scenarios where low power does not compromise integrity.
