Library of self-test software functions and guidelines to assist in 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 software routines can be implemented in any system for self-testing of Synergy S7G2 MCUs. The routines are to be used after reset and during program execution but can be integrated into the overall system design as desired.


The diagnostics software library contains software tests for:

  • CPU
  • Volatile memory (user RAM)
  • Non-volatile memory (Flash ROM for code and data storage)
  • Clock Frequency Accuracy Measurement Circuit (CAC)
  • Independent Watchdog (IWDT)
  • Low Voltage Detection (LVD) module
