Cadence Design Systems Inc. has rolled out its automotive functional safety verification solution that claims to minimise the effort required by automotive designers to prepare for ISO 26262 compliance by up to 50 per cent. The fault injection and safety verification technologies are an expansion to the Cadence Incisive functional verification platform, which aim to help automotive engineers automate ISO 26262 compliance for traceability, safety verification and tool confidence level (TCL), stated the company.

The integrated Cadence Incisive functional safety solution reduces the compliance effort by automating the time-intensive manual verification process of fault injection and result analysis for IP, SoC and system designs. The solution includes the Incisive Functional Safety Simulator and the Functional Safety Analysis capability in the Incisive vManager solution. The simulator operates within the Incisive Enterprise Simulator compiled-code engine, boosting runtime performance up to 10x and providing the seamless reuse of the functional and mixed-signal verification environments to accelerate the time to develop safety verification versus the interpreted Incisive Verifault-XL engine traditionally used in functional safety simulation, Cadence indicated.

The ability of safety systems to detect faults is the critical measurement for ISO 26262 compliance. The Functional Safety Analysis capability allows the safety engineer to automatically generate a safety verification regression from the fault dictionary created by the simulator and enables the Incisive vManager solution to track millions of detected, partially detected and undetected faults introduced into simulation to verify the safety systems in a design. By automating the tracking of these safety metrics, the Incisive functional safety solution automates man-years of effort, and provides the traceable audit trail needed in the systems design chain from semiconductor to OEM suppliers.

The Incisive Functional Safety Simulator and Functional Safety Analysis technologies are part of the Cadence System Development Suite (SDS), addressing the largest and most complex verification and hardware-software co-development challenges faced by semiconductor and system companies.

The Incisive functional safety solution is in limited customer availability. General customer availability is expected in 1H15.
