PWM 01 PUBLIC

V(duty) sets the duty cycle of the PWM output. V(saw) is a 0 to 1V swing sawtooth and sets the PWM frequency. V(amp) sets the amplitude of the PWM output. V(offset) sets the DC offset of the PWM...

Sometimes you have to kick an oscillator out of an initial, metastable state so that it starts reliably at a user defined time in the simulation. This shows a way to do that.
