Hi, I have a signal (eg: sine wave) from signal builder block. When I run the model, I need to check at simulation time 't' (eg. @t=3sec) what is the value of that signal. Based on that value I'll be doing some logic. How can I achieve this?

You can use the Clock Block available in Simulink Library

It gives current time stamp as output.

For more info go to https://in.mathworks.com/help/simulink/slref/clock.html

Please refer Sample Model "Clock.png" attached below!

By using that how I can get my signals magnitude at time 't'? The Clock block can give me current simulation time only.

You can sample the value at that time stamp with the help of a Clock block and trigger subsystem.
