SAFETI_CQKIT: Clarification on Compiler Certification Process with Safeti_CQKit for TMS320F28388D

TMS320F28388D: Certification of STO Process for SIL 3 – Inquiry on Safety-Certified Tools

Tool/software:

Hello,

We are in the process of certifying our Safe Torque Off (STO) implementation for SIL 3 in accordance with IEC 61508.
To achieve this, we require a safety-compliant software development environment, including the IDE, compiler, and C2000Ware.

  • We understand that the compiler can be certified using CQKit with the three templates (TSM, TQP, TQR).
  • For our IDE, we are using CCS 18.0. Could you confirm whether this IDE has any safety certification or if it can be classified as T1 under IEC 61508?
  • Regarding C2000Ware, we are utilizing the following components:
    • Headers: vcu2_crc.h, vcrc_configpoly.h
    • Library: c28x_vcrc_library_fpu64.lib

Could you clarify whether C2000Ware has been safety-certified, or would it be advisable to avoid using it and instead implement the CRC functionality ourselves to meet SIL 3 requirements?

We appreciate your guidance on this matter.

Regards,

Wilko
