This library consists of self-test software functions and guidelines to assist compliance with the IEC 61508 safety standard for industrial systems.

Industrial systems require specific testing to ensure functional safety and fail-safe operation compliance.

The diagnostics software library contains software tests for the CPU, volatile memory (user RAM), non-volatile memory (Flash ROM for code and data storage), Clock Frequency Accuracy Measurement Circuit (CAC), Independent Watchdog (IWDT), and Low Voltage Detection (LVD) module. The software routines can be implemented in any system for self-testing of Synergy S3A7 MCUs.

The routines are to be used after reset and during program execution, but can be integrated into the overall system design as desired.
