Renesas Electronics Corporation recently announced the release of its GUI Customizable Analysis Report (CAR) Tool. It is a special safety analysis tool that would increase the ability of a customer to fastly integrate Renesas products into safety critical automotive systems that would allow them to have more confidence in compliance of system with latest safety standard. The highly powerful  Failure Mode Effects and Diagnostic Analysis (FMEDA) tool has been optimized according to ISO 26262 standards that take care of electrical and electronic systems safety within road vehicles, it is target for revolutionary product compliance.

Renesas is providing an extensive profiel of semiconductor solutions, software, tooling and products in simply every single automotive application. Since CAR Tool addresses a regular market problem - adapting to a general Safety Element out of Context (SEooC) safety analysis report for aligning with final application-specific use case as well as the need for supporting numerous safety goals for a single product.

According to Riccardo Vincelli, the director of the Functional Safety Competence Center, Renesas, “This is a tool developed by safety engineers, deeply involved with the creation of the ISO26262 standard since the beginning, for safety engineers,. It is the result of intensive internal activity to find solutions for daily challenges associated with efficient safety analysis, effective exchange of results with stakeholders, and customization based on different use cases.”

The new CAR Tool brings together the prime aspects of safety analysis by providing a multi-layered view of safety-related component that is completed with customizable analysis parameters and the results needed by ISO 26262 likke LFM (latent fault metric) and SPFM (single point fault metric). It also offers an estimation for probabilistic metric for random hardware failures and their evaluation of every reason for safety goal violation. It simplifies browsing through complex SoC (System-on-Chip) safety analysis.
