safeTbox V3.0 Official Release
We are proud to announce the release of version 3.0 of our safety modeling tool safeTbox™. In this version, the following capabilities have been added:
Modeling capabilities
Hazard and risk assessment (HARA)
In this version, we support hazard and risk assessment according to ISO 26262. This supports the user in the following tasks:
- Functional Hazard Analysis: For selected functions/components, the user can perform a high-level fault analysis with the help of a configurable set of guide words (e.g., Omission, Commission,…). This template allows the user to document the effects of such failures and to determine whether they are safety-critical or not. If they are, the user can also define and associate hazards with them.
- Definition of hazardous events (HE): Given a set of hazards, the user can build hazardous events by defining in which situations these occur. Moreover, the user can also define a hazardous event’s occurrence parameters (e.g., regarding the frequency or the time domain) as well as the expected outcome (e.g., an accident). This implementation also allows the user to define their own scenarios by specifying situation groups (e.g., category Driving Location: highway (over 100 km/h), city (50 km/h),…). The current template makes a clear differentiation between driving and standing situations to simplify the analysis and configuration.
- Definition of safety goals: Having defined the hazardous events, it is then possible to define the severity and the controllability parameters for these HE, for which the system will compute automatically the ASIL. The template allows the user to define safety goals and assumptions related to the assessment of HE.
