FTA Results Page (Gates Only in System Files)
The FTA Results page is shown in the Properties window only for gates in System files because results can be calculated only for System files. Display-only results are shown for the active gate only if quantitative analysis has been performed.
The results that appear depend not only on the FTA calculation type for the System file but also on the FTA calculation properties that were set in the Calculate window when calculations were run.
• For time dependent trees, steady state results for the primary time point appear at the top of the page. A table then displays results for the specified time intervals. You can use the buttons at the bottom of the page to save and print the results in the table. For more information, see
Excel and Print Buttons.
• For Lambda Tau trees, only selected steady state results are shown.
• For SAE trees, only selected probability calculation results are shown.
If the probability value calculated for the gate is less than or equal to its maximum allowable probability, Meets Safety Criteria is set to Yes. Otherwise, it is set to No.
