SafeTkit - First Steps to IEC 61508/ISO 26262

SafeTkit

Making your application safe

The Hitex SafeTkit provides a great introduction to the Infineon PRO-SIL™ safety system for the TriCore and XC2000 microcontroller family by providing the heart of an ASIL-D/SIL3 capable platform in an easy-to-configure and use format.
All the major PRO-SIL™ features are available and can be reconfigured to assess their effect on system behaviour and gain an understanding of the concepts underlying them. The kit contains all the elements required to produce a working application that has the potential for ASIL-D or SIL3 certification (The kit allows the techniques and concepts required for eventual ASIL-D certification to be obtained to be evaluated).

PRO-SIL™
All PRO-SIL™ labeled parts are designed to meet the needs of ISO 26262 and IEC 61508 on the relative architecture.
By using the SafeTcore set of powerful self-test routines that run on the MCU both at startup and cyclically from within an application, the correct operation of the user's software and the CPU itself can be verified.

CIC61508
The CIC61508 safety monitor provides the verification of periodic TriCore/XC2000 CPU tests using a windowed watchdog approach and is able to monitor the TriCore CPU power supply and other critical analog voltages elsewhere in the system.

PRO-SIL Features

  • Satisfies the requirements of ISO 26262 ASIL-D by decomposition
  • Suitable for IEC 61508 SIL3
  • Removes the need for independent hardware safety measures
  • Created using an ISO 26262 development process
  • Externally certifiable
