Where are the sps.*** constants defined in the examples?

In many SimPowersystems examples, there are the constants 'sps.*' which I couldn't find where they are defined. For example, in the "Triangle Generator" block of "PWM_Generator_2Level" example, its frequency and phase parameters are assigned as "sps.Fc" and "sps.Pc". My question is where is the 'sps' defined and how?

Check this video. It was very helpful for me to find the locations of the variables within a model in simulink.
