It’s not enough that the vehicle’s electronic components comply with the ISO 26262 standard. The tools used to develop the components also must be certified (unless the automaker chooses a different approach to functional safety, such as via built-in redundancy). As noted previously, the tools must execute and verify the design flawlessly. To address this, ISO 26262 has a section that covers tool confidence level (TCL), which is defined by tool impact and tool error detection capabilities. Tools in the TCL1 level do not require qualification, while those in TCL2 and TCL3 do, with ASIL determining the qualification methods that are most recommended.
In other words, the design tools themselves are part of the effort to meet ASIL and, ultimately, ISO 26262 requirements. By addressing these requirements, electronic design automation (EDA) and IP vendors can help automotive engineers meet their functional safety objectives and certification —and even accelerate the timeline and efforts to do so. For example, IP provides ready-to-use building blocks that speed up the design process. Automotive-grade IP that meets the stringent guidelines outlined by ISO 26262 puts engineers that much ahead of the game. Some vendors also offer tools to support ASIL planning, design services and tool features that address “what if?” scenarios, and verification/validation solutions that verify an ASIL level has been met.
Synopsys provides the broadest breadth of solutions to help automotive hardware, software, and system designers comply with functional safety standards. Since ISO 26262’s official release, Synopsys has proactively performed ISO 26262-compliance testing and incorporated documentation into our portfolio, which includes:
- ASIL B and D Ready DesignWare® IP portfolio developed and assessed specifically for random hardware faults, including the ASIL D-compliant DesignWare ARC® EM22FS Functional Safety Processor IP, which has been certified for both random hardware faults and ASIL D systematic compliance
- Test automation, simulation, prototyping, and software security testing solutions that are ISO 26262 certified
- Tools certified to ISO 26262 TCL1 to accelerate quality and functional safety qualification
- Comprehensive automotive design solutions that deliver complex functional safety analysis, implementation, and verification capabilities
- Unified functional safety verification platform that brings together technologies for failure modes and effect analysis (FMEA); failure modes, effects and diagnostic analysis (FMEDA); and fault injection campaign management
- Solutions that address reliability challenges, including electromigration, IR drop, device aging, and robust redundant via insertion (RVI) capabilities
These solutions are backed by a team of automotive experts who can work with hardware, software, and system design teams to address their challenges holistically.
