6.2.3. Incorporating Multiplexers

Try these first

1. 1.

   What is the primary function of a multiplexer in a scan chain?

   Hint

   Think about data selection.

2. 2.

   Define 'scan mode' in relation to flip-flops.

   Hint

   Consider how data is managed during testing.

3. 3.

   What does a multiplexer do in a scan chain?

   • It performs arithmetic operations.
   • It selects between different input signals.
   • It stores data.

   Hint

   Consider the function of selector devices.

4. 4.

   True or False: Multiplexers can reduce the number of flip-flops needed in a circuit.

   • True
   • False

   Hint

   Think about efficiency in design.

5. 5.

   Propose an alternative design approach for incorporating multiplexers in large digital circuits while minimizing area consumption.

   Hint

   Consider how designs can be optimized through effective resource management.

6. 6.

   Analyze how using multiplexers in one specific project enhanced test performance, detailing the metrics of success post-implementation.

   Hint

   Think about both qualitative and quantitative improvements in testing outcomes.
