Create models by texts

Now Astah System Safety enables you to create models just by copying and pasting texts.
If you create a list of model names, just copy and paste directly on the diagram.

Then Astah will turn them into Requirements, Blocks and Goals… any models you’d like!

View ASIL History

There are several ways that ASIL are assigned to Requirements. By safety goal, decomposition, and also by directly setting it individually.
Without keeping the track of it, it is not clear how the current ASIL is assigned.
This [ASIL History] view will help to clarify how and why the ASIL is assigned to the Requirement at a glance.

Import UML Profiles

Now you can import UML Profiles to Astah System Safety. This will expand SysML model presentations by using the pre-defined Stereotypes and TaggedValues.
Pre-defined stereotypes are reusable, consistent and you can even set extended properties per stereotype.
