how to simulate a DC buck converter

Hello, all, i am new to the circuitlab. Now i am simulating buck converter, and i want to use a pulse generator and a MOSFET to function as the switch. HOWEVER, where is the pulse generator?

THanks guys

You can use the Digital Clock signal source:

or PWS() source:

or the PWM block:
