Analyzing Propagation From
Interface Propagation Analysis (IPA):
-
- Set count to 0
-
- Select output from distribution OE for component E
- Perturb value of output (simulating E's failure)
- Get results from executing subsystem or system succeeding E
- Compare against PRED; (PRED is defined for system or subsystem); bump count if different
-
- If count > 0, then mitigate.
