Hi guys. I am having a research on optical NoCs and one of its requirements is the scheduling of the packets and I was able to implement a scheduling algorithm in an FPGA. This time, I wanted to interface the FPGA to the optical NoC but the FPGA outputs digital voltage while the NoC needs analog voltage. And that the NoC needs a varying analog voltage because the microring in the NoC needs it for different tuning. Any idea on how to solve this?

Use a DAC.

Depending on the requirements of your device, you might also use the FPGA to generate a pulse width modulation (PWM) signal and then filter that to get your analog voltage. A DAC would be more accurate PWM is easier to implement.
