Launch the Cumulative Damage platform by selecting Analyze > Reliability and Survival > Cumulative Damage. You must supply the Cumulative Damage platform with two data tables as input. The first data table is time-to-event data for each unit under test. The second data table defines the stress patterns used for each unit.

The launch window includes a separate tab for each step-stress data format. For details about the various stress patterns, see Stress Pattern.
