For f = AB+CD if B is S-a-1, what r the test vectors needed
to detect the fault?

Answer Posted / ajit

Walking Ones will find out the Struck-at-1.
0001
0010
0100
1000 : At this point Error will be detected

Or Walking Zero can also find out.
1110
1101
1011 : At this point Error will be detectged
0111
