Each MCU group certification package includes a bundled diagnostic software library and safety documentation, with IEC61508 certification packs from Express Logic for ThreadX RTOS, the X-Ware middleware NetX Duo TCP/IP network stack and the FileX file system.
Renesas’ MCU certification pack includes: a diagnostic software library; a safety manual; and a safety application note document providing guidelines on how to use and configure MCU hardware modules within a functional safety context.
The Express Logic certification packs include complete testing and documented results for all ThreadX services, as well as a description of the process and design methodology. Test source code and test results are included, along with a plan for tool usage, unit and integration test reports, requirements for trace matrix and a safety manual.
According to Renesas, in order to conform with functional safety requirements, system manufacturers need to implement a variety of self-tests down to the device level. Implementing these tests and obtaining detailed safety information from the device manufacturer is said to be significant, enabling faster time-to-market.
