PCIe Tuning Wizard
Figure 26: Launching the Tuning Wizard
The wizard automatically tries different presets and settings and prompts you to reboot the DUT in
the log at the bottom left corner of the wizard. Rebooting the DUT repeatedly is all you will have
to do when using the wizard, and it will prompt you when needed in the log on the bottom left
corner. TraceControl automatically captures and triggers on each boot-up. It stops the capture and
processes the trace to determine if the link is good. During the tuning process, it reports useful
information on the host/target, reports bugs, and produces an equalization verdict and grade for
each side.
Figure 27: Tuning Report
Tuning a system may require from 10 to more than 500 DUT reboots, depending on how difficult
the tuning is. For this reason, it is highly recommended that you automate the DUT reboots and
run the wizard overnight. To do this, click the
auto-reboot options.
