1.5.1. Automated Test Pattern Generation (ATPG)

Try these first

1. 1.

   What does ATPG stand for?

   Hint

   Think about the purpose of ATPG in testing.

2. 2.

   What is the primary function of ATPG?

   Hint

   Focus on what ATPG does in electronic testing.

3. 3.

   What is the main benefit of using ATPG in electronic testing?

   • A. It increases manual labor
   • B. It automates test pattern generation
   • C. It complicates the testing process

   Hint

   Consider how automation affects workload.

4. 4.

   Fault coverage refers to ___

   • True
   • False

   Hint

   Reflect on what it means to have high fault coverage.

5. 5.

   Design a basic ATPG algorithm that generates test patterns for a simple combinational circuit with an XOR gate. Enumerate all the possible faults and the corresponding test vectors needed to identify them.

   Hint

   Consider how each fault modifies expected outputs.

6. 6.

   Explain the impact of not incorporating ATPG in a testing framework for a complex integrated circuit. What challenges might arise?

   Hint

   Consider how automation improves the testing workflow.
