Codethink has provided early access to its mapping between the Eclipse Trustable Software Framework (TSF) and IEC 61508. The mapping establishes a transparent relationship between the engineering principles of the TSF and the objectives defined in IEC 61508, which forms the foundation of many domain-specific safety standards, specifically ISO 26262 for automotive systems.
By making this work available as an early preview, Codethink is inviting organizations interested in applying open source approaches to functional safety to review and begin working with the mapping while the work continues to mature.
“This preview release reflects our belief that trust in software must be engineered in the open. We want organizations working at the cutting edge of safety-critical software to be able to review, evaluate and begin applying these mappings as they evolve,” said Paul Sherwood, chairman of Codethink.
The Eclipse Trustable Software Framework defines six tenets – provenance, construction, changes, expectations, results and confidence – each aligned to the objectives of IEC 61508. This structure enables organizations to connect everyday software development practices with the rigor expected in safety-critical systems.
Codethink plans to contribute the mapping to the Eclipse Trustable Software project once the company has achieved a successful functional safety assessment of CTRL OS using the TSF. This future contribution will build on the baseline assessment achieved last year and represents the next step in validating the framework in a production software environment.
Until that milestone is reached, the mapping is being made available as an early preview for those interested in exploring open, transparent approaches to safety and compliance.
“Our goal is simple, by demonstrating compliance with the Trustable Software Framework, organizations should be able to demonstrate alignment with the world’s most important safety and regulatory standards. Open collaboration is the fastest way to get there,” said Sherwood.
