Is there some way to measure the time difference between two successive rising edges of a pulse train signal using Simulink in MATLAB 7.7 (R2008b)?

I would like to measure the time elapsed between two successive rising edges of a pulse train signal using Simulink in MATLAB 7.7 (R2008b).

Find the attached model that measures the time elapsed between two successive rising edges of a pulse train using Simulink in MATLAB 7.7 (R2008b).

This model consists of a triggered subsystem (triggered on rising edge) that has a pulse train control signal. Whenever there is a rising edge in the pulse train, the subsystem gets triggered. The input to this subsystem is a clock block (which measures the simulation time) and the output is also the same. Thus, whenever there is a rising edge in the pulse train, the subsystem outputs the simulation time. The output is held between successive triggers to the subsystem. This is illustrated by the y axis values in scope1.

The subtract block will provide the time elapsed between two successive rising edges. Scope shows this output.

I am using R2015b and I was able to open it.

Right-clicking on the "detect_time_elapsed.mdl" and saving it as a .mdl model works for me.
