15.11 XOR TREE TEST
An XOR tree is provided in the LM96194 for Automated Test
Equipment (ATE) board level connectivity testing. This allows
the functionality of all digital inputs to be tested in a simple
manner and any pins that are non-functional or shorted to-
The following signals are included in the XOR test tree:
Since the test mode is XOR tree, the order of the signals in
the tree is not important. SMBDAT and SMBCLK should not
be included in the test tree.
To properly implement the XOR TREE test on the PCB, no
pins listed in the tree should be connected directly to power
or ground. If a pin needs to be configured as a permanent low,
such as a GPI, it should be connected to ground through a

low value resister such as 10 kΩ, to allow the ATE (Automatic
Test Equipment) to drive it high.
When generating test waveforms, a typical propagation delay
of 500 ns through the XOR tree should be allowed for.
