found my problem for running faster. It turns out the slope of the
triangle waveform is independent of the period so I had to apply a
greater gain for the sawtooth for it to cross zero. Now I am running at

<div dir="ltr" id="yiv4436180027yui_3_16_0_1_1444926980224_2659">I am
modeling an electrical circuit. I have a voltage across an
inductor being switched on the ground side. I am generating a
pwm using a sawtooth genartor as shown by the attached image.
In my circuit, my PWM switches at 50kHz. When if I set the
sawtooth generator period to > 0.025, the results look as
expected on the graphs. If the sawtooth generate period is
< 0.025, the results are flat; the system can't seem to
calculate at that interval. The period on the timer attached
to the scope is 0.0001.<br clear="none">
