Introduction
Fault Tree Analysis (FTA) uses tree structures to decompose system level failures into combinations of lower-level events, and Boolean gates to model their interactions. The objective of the PCIe link training FTA is to provide the techniques required to troubleshoot the PCIe link training issue with Arria 10 device and resolve it effectively.
Fault Tree Analysis (FTA) for Arria 10 PCIe Link Up Issue
Some of the common PCIe link training issues are:
i) LTSSM failed to reach/stay stably at L0.
ii) Link failed to negotiate to expected speed.
iii) Link failed to negotiate to the expected width.
