What's New
In the 2023 R2 release, Ansys medini analyze extends the efficient, holistic application of safety, reliability, and cybersecurity analysis methods. We've launched a new safety collaboration platform that enables seamless teamwork with a new web-based Digital Safety Manager (DSM).
Fault Tree Performance and Component Fault Tree Evaluations
Increase runtime performance to solve extra-large fault trees—reduce the memory footprint for all fault tree computations. Get a direct evaluation of cut sets and probabilities for Component Fault Trees (CFT).
Structure fault logic inside SysML models, consistently instantiate fault logic and reuse.
Digital Safety Manager Application
The new DSM web application replaces the existing desktop client. Centralized project planning, monitoring, and validation of projects include dedicated KPIs, dashboards, and reporting for safety managers.
Digital Safety Collaboration Platform
Access and control safety and cybersecurity projects with a centralized project portal. Includes collaborative editing with multiple users that connect to the same project using controlled locking.

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
- Digital Safety Management
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.
Ansys Digital Safety Manager recognizes and reflects the way safety teams work every day, not only internally but with their suppliers, assessors, and reviewers. It improves efficiency with traceability and standardization to enable systematic and consistent reuse of safety plans and work products.

Integrating Safety Analysis in an MBSE Process
Safety is a crucial property for many products, especially in the aerospace and defense industry, essential to obtaining the necessary certification. To identify appropriate safety requirements early in the development process and to be able to demonstrate their fulfillment by design, safety analysis must be well integrated into the system development process in all phases. In a model-based approach that is usually highly iterative, it's a great benefit to base the safety analysis on models. This allows us to deal with changes quickly and always have up-to-date analysis to guide development decisions.
