Creating Failure Models Manually

The TF (Total FIT) failure model is the default generated model for every FTA document. Use this
model to adopt the calculated FIT values from the FMEDA/BOM for the FTA. Furthermore, it is
possible manually to create failure models for each FTA document which can be used by dragging and dropping, or can be assigned in the properties dialog.

1. Open the desired FTA document in the PSS view.

   Open

   

2. Right click on Failure models > New Failure model. - Outcome: the "Add failure model" dialog will open.

3. Choose the failure model type and its values.

4. Click on OK.

Outcome: a new failure model has been added to the FTA document.
