I'm trying to design a circuit for my college project.
My load is purely resistive, so in theory, the waveform I should see across the resistor will be square-shaped with the same RMS voltage as the supply voltage (Vcc) of the circuit.
However, when I simulate my circuit, the waveforms appear distorted and noisy.
Could someone check if there's something wrong with my circuit or suggest any ideas?

I suspect that I'm also configuring my PWM sources incorrectly, maybe messing up the dead time... it's all a bit confusing.

You can find the schematic through the link below.

Thank you!
