Hi,
How can I build a counter that starts to count from 0 only after a specific start signal and stops after an other signal (by simulink) ?

Perhaps you could use the Counter Free-Running block inside an Enabled Subsystem and construct the enable signals based on your other two signals?

But in this way it counts as simulation time and returns the final count when it is enable, is it? I need that it starts at enable signal.

Are you saying that the subsystem starts executing at the beginning of simulation? No - it depends on whenever the enable signals goes active. So you can construct your enable signal such that the counter only executes for the duration that you want it to.
