TMS320F28379D: GPIO delay when programming LAUNCHXL-F28379D through Simulink C2000 blockset.

Hello E2E Experts.

Good day.

We are exploring a transition from Xilinx SysGen development board to your LAUNCHXL-F28379D. We program our boards through MATLAB/Simulink and try to avoid programming as much as possible. The boards are used for modulation/control of novel power converter topologies.

As with our past research work, the hardware -- including development boards -- are mentioned in the scientific papers and hence TI and the corresponding board will be mentioned in future publications.

Unfortunately, we've encountered a delay problem when trying to output signals using the board's GPIO.

Please see the following Simulink model which simply outputs 2 PWM signals and their Not OVER GPIO.

As can be seen in the following scope, there is around 20 ns delay between each GPIO:
