Why not Sense the output voltage with a separate diode and smaller cap just to sense the voltage alone ?. Depends on what regulation you need. but why add complexity and cost with an fpga. Overthinking ?

I posted the almost-final circuit below, repeated here
The board plugs into a mainframe and needs the FPGA to handshake with the main controller, a MicroZed board. The FPGA allows a lot of features too, like programmable slew rate, cc/cv/cr modes, data logging, things like that. The Efinix part is just $10.
