The user is expected to tailor this sheet to their specific use-case.

The 'Pin Level Tailoring' tab takes the raw (base) package FIT rate and distributes it among each of the pins (or balls) of the device. Each pin gets an equal percentage of the package FIT. The user should use the FMEDA and safety manual to determine which device pins are used in their application for a safety-related function. The device pins that are not used can be marked as "No" for "Safety related HW element to be considered in the analysis?". This removes these pins from the FIT calculation, which affects the safety related FIT and all derived metrics. Additionally, a Safety Mechanism can be applied to each pin to provide diagnostic coverage for pin failures. The list of diagnostics can be found in the "Pin Level Coverage" section in the bottom right of the 'Diagnostic Coverage' tab. TI may pre-populate the pin level tailoring selections in the pin level tailoring tab based on one or more expected use cases for the device. Altering the selection of Safety Mechanisms will impact the package contribution to Probabilistic Metrics for random Hardware Failures (PMHF) and Single Point Fault Metric (SPFM) in the 'Totals - ISO26262' tab.
