The PWM model provides a pulse-width modulated signal with amplitude '1'. The value remains
at '1' for a fraction duty time of the period time. Each duty time ≥1 results to an amplitude
'1'. The phase parameter shifts the positive edge of the PWM. If the phase shift is set to
'0', the PWM value goes up to '1' with the start of every new period. The initial delay value delays
the PWM at simulation start. As long as the simulation time is smaller than the initial
delay, the output of the PWM remains '0'. Please note: The delay behavior of the PWM time
functions differs from the other time functions.
The minimum time step should consider the PWM times. Especially the synchronization on
the edges of the PWM depends on the selected HMIN.
