8 Functional Safety Resources and Examples

TI provides extensive documentation and guidance to assist customers in meeting functional safety goals. As an example, Table 8-1 lists the AM243x and AM64x functional safety resources.

Table 8-1 Functional Safety Design In Collateral
Safety ManualThe functional safety manual provides a detailed listing of device diagnostic capability, recommendations, and implementation guidelines. TI and end-customer responsibilities are defined as well as SEooC system-level design assumptions and design requirements.
FMEDAThe Failure Modes Effects and Diagnostic Analysis (FMEDA) documents SIL or ASIL calculation assumptions. Modeling of FIT rates and diagnostic coverage based on device lifetime, soft errors due to cosmic radiation, operating temperature profile, specific device functions, and pins usage and customer-defined diagnostic is supported.
Safety Analysis ReportThe Safety Analysis report defines the assumptions made in the FMEDA and defines variables that can help tailor the FMEDA to a specific application.
Functional Safety Diagnostic LibraryThe Safety Diagnostic Library (SDL) provides the software and API interfaces for configuring and using the safety diagnostics. Example configuration code for on-chip diagnostics is provided as well as different options for fault detection. The AM243x, AM64x SDL code has been certified SIL-3 by TÜV SÜD.
