4.2 (Random Test Generation)
Recall that the detection probability is d f =
Tf
, where T f is the set
2n
of vectors that can detect fault f, and n is the number of inputs in the
circuit. In this circuit, we have 3 inputs, so there is a total of 8
possible
Solutions to ECE255A HW2
1.
Any s-a-0 on a NAND input is equivalent to the output s-a-1. The output s-a-0 dominates
any input s-a-1. Then a test set that detects all s-a-1 faults also defects all the s-a-0 faults
on NAND inputs and outputs. (Note that a P
3.1 (Parallel Gate Evaluation)
The Z-to-u conversion, i.e., to convert a signal x = x1 x 2 to x = x1 x 2 according to the
following rule,
00 => 00
(0 => 0)
01 => 01
(u => u)
10 => 01
(Z => u)
11 => 11
(1 => 1)
can be realized by
x1 = x1 x 2
x 2 = x1 + x
