Safety Analysis
CAD-IT offers comprehensive safety analysis solutions through our principal partner, Ansys. Ansys’s safety and cybersecurity threat analysis software facilitate model-based safety analysis, safety concept creation, safety management, and cybersecurity assessment for safety-critical electrical and electronic (E/E) and software (SW) controlled systems. By using this software, engineers can deliver safe and secure products, reduce time to market, maximize profit margins, and comply with standards such as ISO 26262, IEC 61508, ARP 4754A/ARP 4761, ISO 21448, and ISO 21434.
CAPABILITIES
Streamline and Automate Functional Safety Analysis
Functional safety standards, like ISO 26262, ensure that safety-critical electronic systems perform reliably over time without failures. Ansys medini analyze identifies potential hazards, assesses risks, and generates safety requirements for implementing countermeasures. It uses various safety analysis techniques, including HAZOP, HARA, FHA, FTA, FME(C)A, and FMEDA, to verify the safety of the system design. This provides traceability, consistency, and automation of previously manual tasks, and generates necessary documentation for the safety case.
Systematic Identification and Consideration of SOTIF Risks
ISO 21448 “Road Vehicles – Safety of the Intended Functionality” (SOTIF) is a standard that ensures vehicle safety in real-world scenarios, accounting for factors like sensor limitations and changes in the road environment. Ansys medini analyze identifies SOTIF risks, plans countermeasures, and traces safety requirements throughout the implementation process using various analysis methods. It enables diverse teams to collaborate seamlessly in meeting functional safety and SOTIF standards across system, electronics, embedded software, and other areas.
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
Semiconductor safety analysts must assess all failure modes to determine how a flaw in a single chip can impact a product’s overall performance. Ansys medini analyze maps the semiconductor design to system components, determines failure rates, and evaluates design weaknesses using a Failure Mode, Effects and Diagnostics Analysis (FMEDA). This helps engineers identify and address design weaknesses in semiconductors, mitigating their impact on safe performance.
Digital Safety Management
Ansys Digital Safety Manager replaces traditional point-tools, providing a comprehensive view of the safety planning process. It defines safety plans, centralizes data, and monitors outcomes to help construct the safety case. This tool improves efficiency and enables systematic and consistent reuse of safety plans and work products, promoting traceability and standardization across teams and suppliers.
