Create models by texts

Now Astah System Safety enables you to create models just by copying and pasting texts.

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.
