9.2. Golden Hardware Reference Design (GHRD)

The GHRD, part of the Golden System Reference Design (GSRD), is an Intel® Quartus® Prime project that contains a full HPS design for the Intel® Agilex™ SoC Development Kit. The GHRD has connections to a boot source, SDRAM memory and other peripherals on the development board.

You must always use a hardware design with the Intel® Agilex™ SoC if you choose to take advantage of the HPS features. The purpose of the hardware design is to configure the SoC, including the FPGA portion, the HPS pin multiplexers and I/Os, and the DDRAM. All software projects depend on a hardware design.

The GHRD is regression tested with every major release of the Quartus Prime Design Suite (QPDS) and includes the latest bug fixes for known hardware issues. As such, the GHRD serves as a known good configuration of a SoC FPGA hardware system.

GUIDELINE: Use the latest GHRD as a baseline for new SoC FPGA hardware projects. You may then modify the design to suit your end application needs.

The GHRD can be obtained from either:
  • Intel® Agilex™ SoC GSRD page on RocketBoards —This location contains the latest version which is the best known configuration.
  • SoC EDS Installation folder—<SoC EDS Installation directory>\examples\hardware\agilex_soc_devkit_ghrd—This location contains the version supported by the corresponding SoC EDS version. This may not be the latest configuration.
