How do I obtain a data point at a certain time from timeseries based on a condition (simulink and matlab)?

I want to obtain the value of f(t) where t is the time that another fcn is equal to zero. I have a simulink model and I am thinking I will need a MatLab script to make this logic work.
To give a background, I want my model integration to "stop" at steady state. For now, I'm using switch blocks/limited integrators, but I can't run the model autonomously (i've been putting in constants).

If I understand your question correctly, you are looking for an Enabled Subsystem. Look for either the Enabled Subsystem or the Enable block in the Simulink Library.
Enable the subsystem when your control signal is equal to zero and evaluate f(t) inside of that subsystem.
