I want to experiment with the asymmetric pwm wave form as in the control suite example. Can I do that easily in VisSim?

    Yes of course. You just need to put an ePWM block into your diagram, right click on it, and configure it like so:

    Above settings will create EPWMA waveform that goes high on pwm counter zero match,and low on CMPA reg up-count match. The EPWMB output wave form goes low on PWM counter zero match and high on CMPB reg up-count match.

    See attached VisSim diagram for TI Launchpad kit below.
