FTA V Series Family Device FPPx16 Configuration Issue

Last Major Update 

AUGUST 14, 2015



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 this debug FTA example is to help troubleshoot and identify issue related to V series family device FPPx8/16/32 configuration issue and resolve it effectively. 

Configuration failure is a very common issue that user might encounter. The complexity of such issue's debugging are due to below factors:

i) Multiple possible root causes 

ii) Difficult to isolate the problem to a specific area of the design. 

iii) Requires significant effort and time to isolate the hypothesis.

Fault Tree Analysis Diagram & Table

The FTA example : FTA_Configuration_StratixV_FPPx16_issue consists of a FTA diagram and table used to debug and root cause the FPPx8/16/32 configuration failure occurs in V series family devices. In the FTA diagram, multiple hypothesis are make based on the failure symptom as described. For each of the hypothesis, it can have 2nd level or up to 3rd level suspects. The FTA diagram will then be converted into a table format to proper keep track of the debug progress. In the FTA table, for every suspect listed , it needs to have some action items to be performed to verify it together with some additional category information to be filled in such as Owner, Target completion date, status/Results, Possible Next Step and Priority level.
