Certified design IP cores save automotive engineers substantial time and expense in developing Functional Safety conforming ASIC- and FPGA-based systems.
Woodcliff Lake, New Jersey — June 5, 2025 — Semiconductor intellectual property core provider CAST has added new products to its already-strong line of Functional Safety certified design IP cores.
The Functional Safety (FuSa) standard governing automotive systems, ISO 26262, defines Automotive Safety Integrity Levels based on the severity, exposure, and controllability of a system or component. These range from ASIL A for the lowest risk — e.g., infotainment — through ASIL D for the greatest risk — e.g., anti-lock braking.
The Functional Safety IP cores CAST provides conform to safety integrity levels from ASIL B to ASIL D and are suitable for a variety of automotive subsystems.
The new ASIL-ready certified cores are:
Their certification has been awarded by the independent testing lab SGS-TÜV Saar, which performs a stringent audit of each core’s safety approach, architecture, and documentation. The core’s ASIL designation reflects conformance to the specific assurance level’s target values for single-point failures and latent failures. On the hardware architecture level, this typically requires the use of double or triple modular redundancy and error correction codes. The required FuSa documentation includes the Failure Mode, Effects, and Diagnostic Analysis (FMEDA) and a Safety Manual.
As with all ASIL or ASIL-ready certified cores, the standard considers each core to be a Safety Element out of Context (SEooC), meaning it is designed for use in a safety-related system, but developed independently of the final system context. System developers thus remain responsible for the safety certification of the entire system in which the core is integrated. The certified cores CAST provides, however, yield substantial savings in system certification: at the core level, they eliminate the challenge of building in the necessary safety features, the effort to produce the required documentation, and the cost and delay needed for testing lab certification.
“The FuSa-certified cores we offer have saved multiple customers countless hours of expert-level work by being designed correctly and including all the deliverables needed to support the ASIL certification of their automotive systems,” said Nikos Zervas, CAST CEO. “We are pleased to satisfy customer requests for these three additional FuSa cores, and we have several additional certifications underway.”
The newly certified cores join CAST’s offering of one of the industry’s broadest ranges of certified FuSa cores, including these ASIL D level cores:
All ship with the necessary FuSa features and documentation. They are available for ASICs or FPGAs, have flexible licensing terms — including royalty-free — and feature industry-leading customer support before and after each purchase.
