ISO 26262 TCL Compliance

Cadence is the first EDA supplier to earn the "Fit for Purpose - Tool Confidence Level" certification up to TCL3, for ISO standards, supporting automotive design from ASIL A through ASIL D.

We provide Functional Safety Documentation Kits to assist automotive suppliers with ASIL certification documentation, streamlining tool use case evaluation, and minimizing tool qualification activities. These kits, evaluated by TÜV SÜD for both current and future tool versions, cover the full spectrum of design and verification and include a safety manual, tool classification analysis documents, and a TÜV SÜD compliance report.
