Table 732. XOR Test Pattern Example
November 2007
Order Number: 300641-004US
In this example, Vector 1 applies all “0s”
to the chain inputs. The outputs being
non-inverting, will consistently produce a
“1” at the XOR output on a good board.
Likewise, applying Vector 7 (all “1s”) to the chain inputs (given that there are an even
number of input signals in the chain), will consistently produce a “1” at the XOR chain
output on a good board. One short to Vss (or open floating to Vss) will result in a “0” at
the chain output, signaling a defect. It is important to note that the number of inputs
pulled to “1” will affect the expected chain output value. If the number of chain inputs
pulled to “1” is even, then expect “1” at the output. If the number of chain inputs pulled
to “1” is odd, expect “0” at the output.
Continuing with the example in
chain in sequence, the XOR Output will toggle between “0” and “1.” Any break in the
toggling sequence (e.g., “1011”) will identify the location of the short or open.
