10.2.2. Test Compression and Minimization

Try these first

1. 1.

   What is test compression?

   Hint

   Think about how data size can be managed in testing.

2. 2.

   Name one technique of test pattern compression.

   Hint

   Consider methods that replace sequences of data.

3. 3.

   What is the advantage of test compression?

   • Increased testing time
   • Reduced size of test data
   • Higher costs

   Hint

   Think about how compression affects data handling.

4. 4.

   True or False: Test minimization aims to increase the number of test vectors.

   • True
   • False

   Hint

   Consider the term 'minimization' in this context.

5. 5.

   A particular circuit design requires 1,000 unique test vectors. If a greedy algorithm reduces this to 850 while maintaining coverage, what percentage reduction has occurred?

   Hint

   Use the formula for percentage change.

6. 6.

   A test data set consists of the sequence: 0, 0, 1, 1, 1, 0, 0, 0. How would run-length encoding represent this sequence?

   Hint

   Think about summarizing groups of items.
