• Long Fine Tune - This option is identical to the Fine Tune Previous Results option but takes more
time in running the tuning test iterations as compared to Fine Tune Previous Results. Long Fine
Tune, therefore, requires considerably longer time to complete the tuning process than the
Fine tune but can reduce the trace errors resulting from inadequate tuning. You should use this
option only if you are getting excessive errors in the captured traces even after a successful
completion of Fine Tune Previous Results run with all lanes converged. This option is not
recommended for use if all the lanes are not converged.
Click the icon displayed with the Output PTU File field to browse and specify the name and
location for the .ptu file.
The tuning process starts. The Tuning Log section displays the results of the tuning process run
operation. If the tuning process completes successfully, the specified .ptu file gets created. A
tuning log file is also created with the same name and location as the tuning file.
