3.3. Testing Methodologies

Try these first

1. 1.

   What is functional testing?

   Hint

   Think about input and output verification.

2. 2.

   Define Boundary Scan Testing.

   Hint

   Consider how you would access internal parts of a circuit.

3. 3.

   What does functional testing assess?

   • Internal structure of a circuit
   • Input-output performance
   • Electrical parameters

   Hint

   Consider the basic purpose of testing.

4. 4.

   True or False: Structural testing is also known as black-box testing.

   • True
   • False

   Hint

   Think about the ‘color’ metaphor.

5. 5.

   You are tasked with testing a complex digital circuit with multiple ICs. Discuss how you would combine JTAG with parametric testing to ensure thorough coverage.

   Hint

   Think about how to leverage boundary access for comprehensive testing.

6. 6.

   Design a testing strategy for an embedded system that can only be accessed in the field. Which methodologies would you prioritize and why?

   Hint

   Consider the practical limitations of field testing.
