Infineon provides Functional Safety Self-Test Library (STL) to help customers achieve their functional safety goals. This library supports a wide range of Infineon microcontrollers and makes use of its advanced hardware features to provide functional safety mechanisms for a variety of end applications.

Together with ModusToolbox?, it provides a robust ecosystem to achieve IEC 60730 Class B and IEC 61508 SIL certifications.

Self-Test Library Key Features

  • CPU registers: Test for stuck bits
  • Program Counter: test for jumps to the correct address
  • Program Flow: checks correct firmware program flow
  • Interrupt Handling and Execution: tests proper interrupt calling and periodicity
  • Flash (invariable memory): memory corruption check
  • SRAM (variable memory): test for stuck bits and proper memory addressing
  • Stack Overflow: checks stack overflow with the program data memory during program execution
  • Digital I/O: test for pins short
  • Comprehensive Peripheral Self-Test:
    • Analog, TCPWM, CORDIC, I2C, SPI, CAN, UART loopback, and others
