Are you struggling to deal with the issue of failure detection and recovery, including the challenge of hard- and software integration in the context of ISO 26262? What is being done within your company to move from risk analysis to technical product implementation? To help tackle these key challenges, Jeff Hutton, Senior Director at Synopsys Inc. in the United States made a presentation on the topic of "Automotive Fault Analysis Solution: Model Based Development & Verification in the Context of ISO 26262" The presentation goes into detail about the following core issues • Overcoming automotive systems & functional failure: System complexity, fault propagation & analysis • Increased test coverage for hardware & software failure using automated fault insertion scenarios • Development & verification of functional safety concepts to achieve safety goals and required ASIL • The concept & benefits of virtual prototypes • Automated reporting features to meet challenging documentation requirements of ISO 26262 standard >> Download the full presentation for free here: http://bit.ly/HuttonPP

• All safety critical faults must be
identified, analyzed & assessed
• Safety mechanisms must cover
safety relevant faults to prevent
violation of safety goals
• ISO 26262 metrics to be met
• Technical feasibility of functional
safety requirements
• Immense testing effort & resource
limitations
• Time to market constraints
• Product cost must be competitive

Diversity of Failure
• Systematic Hardware (HW) Failure
• Random HW Failure
• Systematic Software (SW) Failure
Tight HW & SW Interaction
Example 1: Falsified signal due to
random HW failure in sensor -> faulty
data properly processed by SW &
distributed to vehicle system
Example 2: Systematic SW failure in
signal processing algorithm causing
falsification of original sensor signal and
causing fault propagation up to system
level
Multi Level HW/SW Task
• Multi-level HW/SW analysis required
• Integrated solution needed to analyze
the impact of faults and to
develop/verify safety concepts
