Cadence Design Systems, Inc. today announced that its Cadence Automotive Solution has been used by ROHM CO., Ltd. for safety verification, a critical component of its ISO 26262-compliant tool chain for automotive LSIs. The ROHM flow, which has achieved ASIL D certification from TÜV Rheinland, a global leader in independent inspection services, utilises Cadence fault injection simulation technology, which can reduce the effort required to complete the safety verification process by up to 50 per cent for automotive applications.
ROHM will be presenting additional details on this use-case at CDNLive Japan 2018 being held at the Yokohama Bay Tokyu Hotel on July 20, 2018.
The flow from ROHM utilised Cadence Incisive functional safety technology to achieve ASIL D certification, the highest level for automotive functional safety. Software validation of the Safety Verification component of the Cadence Automotive Solution, including fault injections, was critical in meeting TÜV Rheinland’s certification requirements. Cadence fault simulation technology effectively addresses many complexities associated with automotive design verification. The simulator allows for successful fault effect analysis for various fault modes, including single event transient (SET), single event upset (SEU), stuck-at 0/stuck-at 1, and dual-point faults, while outperforming existing design-for-test (DFT)-based flows for safety-related fault effect analysis.
“With this new certification from TÜV Rheinland, our customers can be assured that our new LSIs for the automotive market are designed with the highest specifications for automotive safety,” stated Nobuhiro Kanai, LSI Headquarters head of Product Development, ROHM Co., Ltd. “Our flow, utilising the Cadence Automotive Solution’s safety verification component, has been designed to be compliant with the new, second edition of ISO 26262, which will be released in 2018. Fault injection is a mandatory feature for achieving ASIL D certification and compliance with the second edition of the ISO 26262 standard. Additionally, the Cadence solution enabled us to do fault injection simulation using the same testbench, design and debugging environment, which significantly speeds our verification process.”
The Cadence Automotive Solution’s Safety Verification flow automates what can otherwise be a manual, time-consuming process for achieving ISO 26262 functional safety compliance. The solution is part of the Cadence Verification Suite’s application-optimised solution for automotive devices. It also supports the company’s System Design Enablement strategy, which enables system and semiconductor companies to create complete, differentiated end products more efficiently.
