Conducting of SW Hazan and
Fault Insertion Tests

  • The Software HAZAN (Keyword-driven HAZard ANalysis) is an advanced technique evaluating the behavior of critical SW functions under expected fault conditions. Given the expected fault conditions it can be determined if sufficient protection measures are in place to combat these fault conditions. The list of protection measures helps in creating a checklist for integration testing.
  • Customer and Exida engineers will review the SW architecture and source code structure, and collect arguments for detection and containment of potential systematic problems.
  • The deliverable of this task is the SW HAZAN report, listing all runtime safety integrity measures that must be implemented, and a list of Fault Injection Tests.

exida Tools

  • SW HAZAN tool with a database of functional failure modules of SW functions
