Question:
Logical test of some faults of a full-adder This exercise invites you to test the full-adder of wh ich the logic diagram is given again in Figure 13.21.
1. Find all the input vectors which test the stuck-at '0' fault a in the figure.
2. This fault has already been studied in Exercise 5.2 of Chapter 5. In what way is this functional approach different to the present structural path sensitizing approach?
3. A functional fault transformed the two EXCLUSIVE OR gates into IDENTITY gates. 1s it possible that a test vector that was found In question 1) can test this fault, which is not a stuck-at fault? Why?
