Worked Example
default_test
Given:
- t_up = 0.8
- t_down = 1.2
Expected Result:
- coordination_time_margin = 0.4
Engineering Interpretation:
Under the given input conditions, the calculated result is: coordination_time_margin = 0.4 s.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
