Software
Use of official compliance test software is recommended, but not required. While manually
measuring the signal might be just as effective, it must ultimately pass with the compliance
software.
Table 5 contains a list of the recommended test software.

Platform
NVIDIA PATCH-A (mandatory) Patch to OS- PCIe driver to avoid PCIe controller power
down for Orin Tx testing for Orin as DUT. Use the patch for
the OS release being used. Open a BUG to track PATCH-A
release.
NVIDIA PATCH-B (mandatory
for Gen3 Sigtest)
Patch to OS- to disable Orin SSC on RefCLK. In some
cases, SSC for the Orin module RefCLK must be disabled
for Sigtest measurement. Use the proper patch for the OS
release being used.
