Actions and Recommendations from the MoniMods Dependability Analysis

A = proposed Action; R = Recommendation TBD ; see also full report

To be checked if completed or strikethrough if obsolete

• [A] Implementation of a MoniMod sanity check on the DI/OT system board and issuing of a warning when a MoniMod gets lost. (Issue duplicated on both system boards' OHWR pages)
• [R, optional] Use of automotive grade oscillators for lower drift and higher reliability (AEC‑Q200).
• [A] Tests at top performance parameters for functional validation of the MoniMod designs.
• [A] Validation tests at determined environmental stress limits (see here) and top performance.
• [A] High stress tests to determine the robustness and sufficient margin for both functional errors and hardware failures against different stresses.
• [A] High quality requirements during the PCB and PCBA production process (IPC class 3 TBD), supported by a high level of inspections. Final End‑of‑Line functional test bench (“PTS”) TBD.
• [A] Screening (temperature cycling) and reliability testing (run in) as outlined in here.
• [R] Comprehensive failure monitoring, root-cause analysis and failure data analysis (Weibull analysis) for all units installed.
