Problems with connecting F28335 1-ph PWM from Simplified C block output

Hello everyone,

Currently, I am using the simcoder function to generate control signals. I first convert the voltage value that needs to be detected in the hardware circuit into digital data through the ADC converter, and then send it to the Simplified C block for processing. In this step, UE1 is the same as the original waveform(V14). The shapes are the same, as shown in the figure.

However, when I want to take the next step and send it to F28335 1ph-PWM, my ue1 waveform is not the same as the original waveform, as shown in the figure.

    Hi,

    Are you trying to simulate existing example?

    It's not clear that where you are measuring these signals in schematic.

    Thank you,
