Saving And Loading Settings
You can store your current settings using the “Apply and Save...”
button in the main window, or via the main menu. Note that before
the settings are saved, they are applied to the hardware. Only if
applying succeeds, the settings can be saved. This guarantees that
only those settings can be saved which are in a consistent state.
The settings can be restored at any time using the “Load and Apply...”
button. The restored settings are then immediately applied to the
hardware.
Expert Mode
In the "Options" menu, you can enable "Expert Mode". This mode is
recommended for advanced users and offers you some more
parameters to modify. The main advantage of the Expert Mode is the
possibility to edit the link training sequence and pattern using a
special script.
Exporting The Script
Once you found a link training sequence suitable for your needs, you
may want to export this sequence, e. g. for later use or to export it to
the automated test solution software.
To export the current script, click “File”, then “Export Script”. This
saves the currently used script for the training sequence to a file,
regardless whether you defined it via parameters or editing the PCIe
or generic script. Please refer to the next section for details about
scripts.
Script Editing
The main advantage of the Expert Mode is the possibility to edit the
link training sequence and pattern using a script. This allows you to
define virtually any kind of pattern, whereas the methods mentioned
earlier in this document only allow to generate patterns which are in
sync with the PCIe link training methodology.
In order to be able to edit the script, Expert mode must be enabled,
and the script must be defined as the source of the pattern. By
default, the pattern that is downloaded to the J-BERT is defined via
parameters, like the “PCI Express Training Parameters” box.
However, in Expert Mode the group box “Pattern/Sequence Script”
becomes available (Figure 17).
