Super ContributorCyclone 10 GX, Arria 10 and Agilex have specific requirements for power rail sequencing, partly including power-down sequence specifications. Active discharge can be required to fulfill it. I feel that respective device handbooks give detailed reasoning which parameters should be implemented.
Can you tell which DE10 board schematic are you quoting?

Regular ContributorHi sovad,
Just checking if there is any update from your side.
As Frank mentioned, some FPGA families such as Cyclone 10 GX, Arria 10, and Agilex may have specific power sequencing or power-down requirements. In some designs, an active discharge circuit can help meet these requirements by discharging the power rails faster.
For the Terasic DE10 board, the exact reason depends on the specific schematic and Terasic’s board-level design. Please check with Terasic if you need confirmation on their implementation.
Since there has been no further response, we will consider this thread closed. If you have any further questions, please feel free to post a new update.
