Version 3.2

– Export of HARA artifacts as Excel spreadsheets
– Introduction of individual set of settings for HARA sheets Sorting functionality in the sheets have been enhanced
– Context menus have been reorganized

– Extended automation for GSN goals:  goals become automatically public when connecting goals to module elements. Moreover, an away goal will be automatically added to the module referencing the given goal.

– Enhanced the CFT analysis results by adding the parent paths of the prime implicants, to provide more detailed analysis results.

– Reproduce Ports layout between classifiers and instances in both directions.
– Connect automatically the ports at component models and component fault trees (CFTs) by using different strategies
– Cloning of realization views allows you to decide for partial and full cloning of interfaces.

Bug and issues corrections
– GSN referencing issues
– Corrected loop detection mechanisms
– Over-controlling modelling for SysML avoided.
– HARA ASIL selection

Version 3.1

– Modules support now multiple realization views. e.g. to create variants
– Drag and drop modeling has been enhanced

– The parent failure view generation process has been enhanced, so the user can more easily find the right view to be instantiated.

– A new editor to perform bulk changes has been added “Table view”
– The smart menu has been reworked, so it appears more condensed
– A quick search feature has been added
– The show/hide embedded elements (primary for component entities) has been enhanced
– Now the element selection list includes a filtering mechanism
– The shortcuts in the tool have been reworked

Version 3.0

– A new set of editors have been added to support the Hazard and Risk Assessment according to the ISO 26262

– Common Cause Failure Analysis has been included as part of component fault trees.

– Now component models and CFTs support multiple realization views. This is handy to depict multiple variants, and handling model complexity. e.g. due to the connection to multiple hazards.
– Elements can now be freely visualized (i.e. background, border colors.)
– A new element explorer has been added. Excel import included
– Spell checking has been added to the STB properties view
– Multiple Dialogs have been reworked.

Version 2.0

– A new set of editors have been added to support the construction of structured arguments according to the GSN standard 1.0.

– New the user has the possibility to set failure type systems and assign these to the fault tree models.
– Integration with the Reliability Workbench/FaultTree+ V13 has been achieved.

– A user experience performance program has been added to the tool. This will allow the development team understand better the end users.
– Now users can upgrade and downgrade between projects created with different versions of the tool.
– A properties view has been added as complement to the existing properties dialog.
