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 Opencl related such as setup, installation, compilation and runtime. This FTA includes most of the common issue face when a new user started to use the Altera Open CL SDK package.
Fault Tree Analysis Diagram & Table
The FTA example : FTA_opencl_for_new_userconsists of a FTA diagram and table used to debug and root cause the Open CL common issues. In the FTA diagram, multiple hypothesis or category are made based on the failure symptom as described. For each of the hypothesis, it can have second level or up to third 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.
