What's New
Ansys medini analyze enhancements:
- System weakness analysis to better identify and address limitations of the System elements, and their triggering conditions, so teams can satisfy Safety of the Intended Functionality (SOTIF) standard requirements.
- Determine critical paths that lead to system failure with the new FTA Heatmap. Analysts can visualize and trace single and multipoint faults throughout design models.
- Streamlined chip design import to enable functional Safety analysis of the entire electronics architecture — including down to the chip level
- Combined safety and cybersecurity analysis in one project to connect cyber threats to potential Safety hazard

Capabilities
The Ansys Safety Analysis software suite streamlines safety and security analysis, decreasing efforts and costs.
- Streamline and automate functional safety analysis
- Systematic identification and consideration of SOTIF risks
- Systematic cybersecurity threat analysis and risk assessment
- Assess the functional safety of semiconductors
During system design, safety analyses (HAZOP, HARA, FHA, FTA, FME(C)A, FMEDA, etc.) are applied to verify that the design is safe. This enables full traceability, consistency and automation of previously time-consuming and error-prone manual tasks. Necessary documentation of the safety case is generated by the tool.
Ansys medini analyze enables the systematic identification of SOTIF risks in the hazard and risk analysis stage, as well as the consideration of design limitations and triggering conditions. Once these are identified, countermeasures can be planned to meet safety requirements. These measures and requirements are traced in Ansys medini analyze to the functional or architectural updates that are completed during the implementation of the system. Ansys medini analyze provides analysis methods like cause-effect-nets, System Weakness Analysis tables, and event trees, which make systematic analysis, understanding and elimination of SOTIF hazards possible.
This enables diverse teams — working to meet functional safety and SOTIF standards across system, electronics, embedded software, and other areas — to collaborate easily and more seamlessly.
This model-based, integrated tool provides end-to-end traceability, along with powerful collaboration, task management and reporting capabilities.
Ansys medini analyzes capabilities for semiconductors facilitate the process of mapping blocks of the semiconductor design to system components. Furthermore, it determines failure rates for the overall chip design and distributes it according to criteria, as die area occupation or gate count to the functional blocks. In a subsequent step, a Failure Mode, Effects and Diagnostics Analysis (FMEDA) can be done to evaluate the overall design with respect to the coverage rates of failure modes by safety mechanisms. In this manner, engineers can quickly identify any design weaknesses in semiconductors, whether caused by design errors or environmental conditions, and address them to mitigate the impact on day-to-day safe performance.
