1.3.3. FPGA Power Off Step 1: Board Design (Power Rail) Choices

The Cyclone V SoC supports combining power rails for the HPS and FPGA. To implement FPGA Power Down Mode, be sure to provide separate power sources for all rails that can be shared between the HPS and FPGA circuitry. Good references to follow are available as part of the Cyclone V SoC Development Kit download, which can be found on the Cyclone V SoC Development Kit and SoC Embedded Design Suite web page.

Altera recommends using Altera's Enpirion® Power Solutions for the required Cyclone V SoC power rails. Altera provides several resources to assist with understanding your Cyclone V SoC power requirements as well as selecting components for and designing a suitable power tree. These resources can be found at Altera's Powering FPGAs Resource Center web page.
