Error-Model Annex v2
The support of the Error-Model Annex is done by several means:index.html
Functional Hazard Assessment support
for producing reliability report of your architecture.
Fault Impact traces
the error path from error sources to the final component impact by the fault.
Unhandled faults report
traces and logs potential modeling problems related to the error description
of the system architecture.
Consistency Checks reports
any discrepancy and inconsistency between the different error notations
(component error model, composite error model, etc.).
Fault-Tree Analysis support
for producing fault-tree representation from the AADL model.
Instance Model Viewer support
for viewing error and their propagations in the underlying architecture.
Reliability Block Diagram: provides
metrics about the overall reliability of the system, based on a gross
PRISM export: export an AADL
model into a PRISM model to process model-checking method using the Markov-Chain
formalism. We also explain the mapping into CTMC
These functionalities are available in the Fault Analysis menu from OSATE, as shown in the
following picture. Note that most of functions apply to the instance model. To use
them, you will need to select the system instance and run the expected analysis.
