The safety engineer edits an FMEDA, assigns calculation parameter values and diagnoses to a FMEDA
document with the calculation scheme ISO 26262. SOX then performs the calculations accordingly
and displays the results.

Prerequisites: an FMEDA document with calculation scheme ISO 26262 is open. Diagnoses were created. Safety goals were assigned.

 

  1. Double-click to set the diagnosis.

  2. Double-click to set the safety relevance SR (SP).

  3. Enter the relevance (optional).

  4. Enter FMC (SP).
    Do the same steps for MP.

  5. Set CCF.

Outcome: SOX calculates the resulting metrics λ and displays them.
