In SIMULINK, how can I get the time corresponding to my particular output of of a function block?

For example I have my function y=f(t) and I want to assign the time corresponding to y=k, to T1. k is const.

I would use a Triggered Subsystem to do this. The subsystem would be driven by a rising edge in the comparison y=k, so that when this becomes true, the subsystem executes.

Inside the Subsystem, you could put in a "Clock" block so when the subsystem executes, the time is output.

One other note, you may want to do the comparison either with some tolerance or as a "greater than or equal", so you don't miss the event.

I am not able to implement it, can you please illustrate with an example

Sure -- it would look as below.

The contents of the Triggered Subsystem are literally just passing the input right through the output. Essentially, it "grabs" the clock value when the trigger event occurs.
