Available Kit and Related Services

IEC61508 Certification Kit for RX Compilers

This kit supports the certification of development tools which are required for the IEC 61508 functional safety standard. Writing software that must satisfy functional safety standards requires verification of the compiler generating code which is safe in the stipulated ways. Renesas offers a C compiler that is certified for functional safety to IEC 61508 Safety Integrity Level (SIL) 3.

Renesas also offers RX Functional Safety, a suite of programs and documents, as a functional safety solution for industrial automation.

For details of this functional safety solution, refer to this page. >>

Compiler Qualification (Service to Support Functional Safety)

For customers who are using a compiler for Renesas devices, we offer a support service for the qualification of confidence that development tools meet the requirements of ISO 26262, Road Vehicles Functional Safety. This service incurs a charge.

Assistance with Compiler Migration

The IDEs from Renesas (such as the e² studio and CS+) allow for the porting of projects between IDEs to facilitate the reuse of existing resources. Refer to the guidance page of migration when changing your compiler after changing your development environment. The guidance page describes precautions that must be taken when changing compilers, such as differences in options and in extended language specifications.
