Functional test and toggle test 0/ a Jull-adder 1. Find a very simple functional sequence of two vectors to test the fulladder of the previous exercise. Find the stuck-at faults detected by this sequence.

2. Complete the previous sequence in order to obtain a toggle type test sequence (such a sequence was found in Exercise 12.2 of Chapter 12).

3. Complete the previous sequence to test all the stuck-at faults of the circuit.
