IEC61508 SIL3 Fundamental Technology

●Safety Package

The Safety Package provides a self-test diagnostic software library for microcontroller and a complete safety manual. The package has been IEC61508 SIL3 certified by TUV Rheinland. For safe system development, developers can select the information they require from the safety manual and make use of the self-test diagnostic software library to alleviate the burden on microcontroller-level development to confirm to functional safety.

• Diagnosis targets
  

  

• Test timing
  • - At start up, Interval execution after start up
• Running of Test condition
  • - All execution or division execution
• Development tool (C compiler)
  • - Renesas CC-RX compiler for functional safety
  • - IAR Embedded Workbench^® for RX FS

●CC-RX Compiler for Functional Safety

For constructing software in the functional safety system, it is necessary to prove that the compiler generates valid code. Renesas offers IEC61508 certified C compiler for functional safety.

IEC61508 SIL3 Reference Kit

Renesas has documented safety system specifications and specifications for its implementation, and based on these has performed detailed design, safety analysis, and diagnostics on a dual structure of microcontroller hardware and software. These results are offered as a safety reference kit. By using the safety reference kit as a template, the developer can vastly reduce the system development time. The content and format of the safety requirements specifications and safety concept of the documents have been verified by TUV Rheinland, so it is easy for developers who are aiming for system certification to use.
