5.14.7 Auto-Configure Lane Polarity
Lets the Analyzer determine lane polarity (see Figure 5.1 on page 48 : 3G). Auto functions
such as Auto Configure polarity rely on Gen1 or Gen2 training sequences to properly
discover their values. If the speed option is set to fixed Gen3, the analyzer will never see
these sequences and the polarity discovery will not be reported properly in the
dashboard dialog.
5.14.8 Ignore Idle Errors
When set the analyzer will not store errors in between packets in the memory. This
option helps to preserve analyzer memory to store more packets in cases where memory
efficiency is critical. This option can also be used to filter out Compliance Patterns (see
Figure 5.1 on page 48 : 3H).
5.14.9 Swizzling Config...
The Swizzling Config dialog allows you to reconfigure the order of the US (UpStream) and
DS (DownStream) lanes (see
Figure 5.12 on page 58 ).
Check the box to Auto‐Configure Lane Swizzle (see Figure 5.1 on page 48 : 3I). Note:
Autoswizzle works only when the analyzer sees LTSSM Configuration state link training
sequence.
Figure 5.12: Swizzling Config Dialog
When the Auto‐Configure Lane Swizzle is checked, it is important to configure Lane 0. You
can do so by manually dragging Lane 0 to the required position.
