6.3.2. Power Consumption During Testing

Try these first

1. 1.

   What is power gating?

   Hint

   Think about power management strategies.

2. 2.

   Name one technique to minimize power consumption during testing.

   Hint

   Focus on data shifting activities.

3. 3.

   What is the primary concern with power consumption during testing in scan chains?

   • Increased testing time
   • Reduced device performance
   • High energy usage

   Hint

   Consider impacts on battery-operated devices.

4. 4.

   True or False: Test pattern compression can help reduce power consumption during testing.

   • True
   • False

   Hint

   Reflect on how data processing affects energy consumption.

5. 5.

   Design a theoretical system with a scan chain that reduces power consumption using both test pattern compression and power gating. Describe how each technique contributes to efficiency.

   Hint

   Focus on how the combined actions of these techniques lead to energy savings.

6. 6.

   Analyze the potential impacts of excessive power consumption during testing on the overall design lifecycle of a mobile device.

   Hint

   Consider the lifecycle from design to consumer use.
