Capabilities

Key Features

Easily handle the complexity of varied design environments with a range of analytical tools that enable you to meet performance goals and ensure long-term reliability.

Streamline and automate functional safety analysis

Functional safety standards, such as ISO 26262, are critical for ensuring that safety-critical electronic systems are reliably delivering consistent performance over time, without system failures. With Ansys medini analyze, the system functions are analyzed for potential hazards and a risk classification is completed. Subsequently, safety requirements are derived to implement appropriate countermeasures to mitigate the risks.

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.

Systematic identification and consideration of SOTIF risks

ISO 21448 “Road Vehicles – Safety of the Intended Functionality” (SOTIF) is a new standard that examines whether a system is sufficiently safe even in the absence of failures when hazards are caused by e.g. performance limitations of sensors or perception algorithms, unexpected changes in the road environment, etc. It enables engineering teams to avoid situations where vehicles are working as designed, but are falling short under real-world scenarios.

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.

Systematic cybersecurity threat analysis and risk assessment

The key to ensuring the cybersecurity of systems is to systematically perform threat analyses and risk assessment across the entire electronics architecture. By identifying every possible means of cyberattack — and estimating both their impact and their feasibility — Ansys medini analyze protects against damaging threats.

This model-based, integrated tool provides end-to-end traceability, along with powerful collaboration, task management and reporting capabilities.

Assess the functional safety of semiconductors

Safety analysts must look beneath the surface of semiconductors to assess all failure modes and determine how a flaw in a single chip could manifest itself in a product’s overall performance.

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.

Digital Safety Management

Safety and engineering teams can get a comprehensive view of the entire safety planning process – beyond the individual project level. By replacing traditional point-tools, Ansys Digital Safety Manager defines safety plans, controls their execution, centralizes data and monitors outcomes. It helps to construct the safety case by providing efficient automations.

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.
