5.5.2. Testing of Analog or Mixed-Signal Systems

Try these first

1. 1.

   What is the primary difference between analog and digital signals?

   Hint

   Think about how data is represented in each type.

2. 2.

   Name one testing method used for analog circuits.

   Hint

   Consider instruments that measure electrical properties.

3. 3.

   Which testing methods are most often used for digital circuits?

   • Scan chains
   • Direct measurements
   • Functional testing

   Hint

   Think about the methodologies most suited for binary signals.

4. 4.

   True or False: All circuits can be tested using the same method.

   • True
   • False

   Hint

   Consider the differences in signal characteristics between analog and digital.

5. 5.

   Given a mixed-signal system, outline a full testing plan that incorporates both digital and analog testing methodologies.

   Hint

   Think of how each type of signal interacts while testing.

6. 6.

   How would the presence of parasitic elements in an analog circuit affect the accuracy of testing? Provide an example.

   Hint

   Consider the unintended consequences of physical connections.
