In order for auto calibration at Gen3 to work, lane polarity has to be set manually. In
general, follow the steps below to find the polarity and set it up properly in the calibration
dialog.
1. Setup the analyzer to record the training sequence with (TS2, Switch to G3 or
InitFC1), at Gen1 or Gen2 (use trigger as TS2 or Speed Switch), using the Auto‐
Configure Lane Polarity recording option. This will allow the analyzer to calculate/
determine the polarity and lane reversal settings of the link.
